    .https_only()
    .enable_http1()
    .enable_http2()
    .build();
let hyper_client = HyperClientBuilder::new().build(https_connector);

// This connector can then be given to a generated service Config
let config = my_service_client::Config::builder()
    .endpoint_url("https://example.com")
    .http_client(hyper_client)
    .build();
let client = my_service_client::Client::from_conf(config);

    let https_connector = hyper_rustls::HttpsConnectorBuilder::new()
        .with_webpki_roots()
        .https_only()
        .enable_http1()

When unset, the client will used a generated endpoint resolver based on the endpoint resolution rules for aws_sdk_s3.

Note: setting an endpoint resolver will replace any endpoint URL that has been set. This method accepts an endpoint resolver specific to this service. If you want to provide a shared endpoint resolver, use Self::set_endpoint_resolver.

Examples

Create a custom endpoint resolver that resolves a different endpoing per-stage, e.g. staging vs. production.

use aws_sdk_s3::config::endpoint::{ResolveEndpoint, EndpointFuture, Params, Endpoint};
#[derive(Debug)]
struct StageResolver { stage: String }
impl ResolveEndpoint for StageResolver {
    fn resolve_endpoint(&self, params: &Params) -> EndpointFuture<'_> {
        let stage = &self.stage;
        EndpointFuture::ready(Ok(Endpoint::builder().url(format!("{stage}.myservice.com")).build()))
    }
}
let resolver = StageResolver { stage: std::env::var("STAGE").unwrap() };
let config = aws_sdk_s3::Config::builder().endpoint_resolver(resolver).build();
let client = aws_sdk_s3::Client::from_conf(config);

pub fn set_endpoint_resolver( &mut self, endpoint_resolver: Option<SharedEndpointResolver>, ) -> &mut Self

    builder.set_retry_config(Some(retry_config));
}

let mut builder = Config::builder();
disable_retries(&mut builder);
let config = builder.build();

Set the sleep_impl for the builder

Examples

use aws_sdk_s3::config::{AsyncSleep, Config, SharedAsyncSleep, Sleep};

#[derive(Debug)]
pub struct ForeverSleep;

impl AsyncSleep for ForeverSleep {
    fn sleep(&self, duration: std::time::Duration) -> Sleep {
        Sleep::new(std::future::pending())
    }
}

let sleep_impl = SharedAsyncSleep::new(ForeverSleep);
let config = Config::builder().sleep_impl(sleep_impl).build();

pub fn set_sleep_impl( &mut self, sleep_impl: Option<SharedAsyncSleep>, ) -> &mut Self

Set the sleep_impl for the builder

Examples

use aws_sdk_s3::config::{AsyncSleep, Builder, Config, SharedAsyncSleep, Sleep};

#[derive(Debug)]
pub struct ForeverSleep;

impl AsyncSleep for ForeverSleep {
    fn sleep(&self, duration: std::time::Duration) -> Sleep {
        Sleep::new(std::future::pending())
    }
}

fn set_never_ending_sleep_impl(builder: &mut Builder) {
    let sleep_impl = SharedAsyncSleep::new(ForeverSleep);
    builder.set_sleep_impl(Some(sleep_impl));
}

let mut builder = Config::builder();
set_never_ending_sleep_impl(&mut builder);
let config = builder.build();

pub fn timeout_config(self, timeout_config: TimeoutConfig) -> Self

Set the timeout_config for the builder

Examples

use aws_sdk_s3::config::Config;
use aws_sdk_s3::config::timeout::TimeoutConfig;

let config = Config::builder().timeout_config(timeout_config).build();

pub fn set_timeout_config( &mut self, timeout_config: Option<TimeoutConfig>, ) -> &mut Self

Set the timeout_config for the builder.

Setting this to None has no effect if another source of configuration has set timeouts. If you are attempting to disable timeouts, use TimeoutConfig::disabled

Examples

use aws_sdk_s3::config::{Builder, Config};
use aws_sdk_s3::config::timeout::TimeoutConfig;

fn set_request_timeout(builder: &mut Builder) {
    let timeout_config = TimeoutConfig::builder()

set_request_timeout(&mut builder);
let config = builder.build();

pub fn retry_partition(self, retry_partition: RetryPartition) -> Self

Set the partition for retry-related state. When clients share a retry partition, they will also share things like token buckets and client rate limiters. By default, all clients for the same service will share a partition.

pub fn set_retry_partition( &mut self, retry_partition: Option<RetryPartition>, ) -> &mut Self

Set the partition for retry-related state. When clients share a retry partition, they will also share things like token buckets and client rate limiters. By default, all clients for the same service will share a partition.

pub fn identity_cache( self, identity_cache: impl ResolveCachedIdentity + 'static, ) -> Self

Set the identity cache for auth.

The identity cache defaults to a lazy caching implementation that will resolve an identity when it is requested, and place it in the cache thereafter. Subsequent requests will take the value from the cache while it is still valid. Once it expires, the next request will result in refreshing the identity.

This configuration allows you to disable or change the default caching mechanism. To use a custom caching mechanism, implement the ResolveCachedIdentity trait and pass that implementation into this function.

Examples

Disabling identity caching:

use aws_sdk_s3::config::IdentityCache;

let config = aws_sdk_s3::Config::builder()
    .identity_cache(IdentityCache::no_cache())
    // ...
    .build();
let client = aws_sdk_s3::Client::from_conf(config);

Customizing lazy caching:

use aws_sdk_s3::config::IdentityCache;
use std::time::Duration;

let config = aws_sdk_s3::Config::builder()
    .identity_cache(
        IdentityCache::lazy()
            // change the load timeout to 10 seconds
            .load_timeout(Duration::from_secs(10))
            .build()
    )
    // ...
    .build();
let client = aws_sdk_s3::Client::from_conf(config);

pub fn set_identity_cache( &mut self, identity_cache: impl ResolveCachedIdentity + 'static, ) -> &mut Self

            .build()
    )
    // ...
    .build();
let client = aws_sdk_s3::Client::from_conf(config);

pub fn interceptor(self, interceptor: impl Intercept + 'static) -> Self

This optional name is used to identify the application in the user agent that gets sent along with requests.

pub fn invocation_id_generator( self, gen: impl InvocationIdGenerator + 'static, ) -> Self

Overrides the default invocation ID generator.

The invocation ID generator generates ID values for the amz-sdk-invocation-id header. By default, this will be a random UUID. Overriding it may be useful in tests that examine the HTTP request and need to be deterministic.

pub fn set_invocation_id_generator( &mut self, gen: Option<SharedInvocationIdGenerator>, ) -> &mut Self

pub fn set_endpoint_url(&mut self, endpoint_url: Option<String>) -> &mut Self

Sets the endpoint URL used to communicate with this service Note: this is used in combination with other endpoint rules, e.g. an API that applies a host-label prefix will be prefixed onto this URL. To fully override the endpoint resolver, use Builder::endpoint_resolver.

pub fn use_dual_stack(self, use_dual_stack: impl Into<bool>) -> Self

When true, use the dual-stack endpoint. If the configured endpoint does not support dual-stack, dispatching the request MAY return an error.

pub fn set_use_dual_stack(&mut self, use_dual_stack: Option<bool>) -> &mut Self

When true, use the dual-stack endpoint. If the configured endpoint does not support dual-stack, dispatching the request MAY return an error.

pub fn use_fips(self, use_fips: impl Into<bool>) -> Self

When true, send this request to the FIPS-compliant regional endpoint. If the configured endpoint does not have a FIPS compliant endpoint, dispatching the request will return an error.

pub fn set_use_fips(&mut self, use_fips: Option<bool>) -> &mut Self

When true, send this request to the FIPS-compliant regional endpoint. If the configured endpoint does not have a FIPS compliant endpoint, dispatching the request will return an error.

pub fn region(self, region: impl Into<Option<Region>>) -> Self

pub fn behavior_version(self, behavior_version: BehaviorVersion) -> Self

Sets the behavior major version.

Over time, new best-practice behaviors are introduced. However, these behaviors might not be backwards compatible. For example, a change which introduces new default timeouts or a new retry-mode for all operations might be the ideal behavior but could break existing applications.

Examples

Set the behavior major version to latest. This is equivalent to enabling the behavior-version-latest cargo feature.

use aws_sdk_s3::config::BehaviorVersion;

let config = aws_sdk_s3::Config::builder()
    .behavior_version(BehaviorVersion::latest())
    // ...
    .build();
let client = aws_sdk_s3::Client::from_conf(config);

let config = aws_sdk_s3::Config::builder()
    .behavior_version(BehaviorVersion::latest())
    // ...
    .build();
let client = aws_sdk_s3::Client::from_conf(config);

Customizing behavior major version:

use aws_sdk_s3::config::BehaviorVersion;

let config = aws_sdk_s3::Config::builder()
    .behavior_version(BehaviorVersion::v2023_11_09())
    // ...
    .build();
let client = aws_sdk_s3::Client::from_conf(config);
