Struct ClientOptions

pub struct ClientOptions { /* private fields */ }

HTTP client configuration for remote catalogs

Implementations

impl ClientOptions

pub fn new() -> Self

Create a new ClientOptions with default values

pub fn with_user_agent(self, agent: HeaderValue) -> Self

Sets the User-Agent header to be used by this client

Default is based on the version of this crate

pub fn with_default_headers(self, headers: HeaderMap) -> Self

Sets the default headers for every request

pub fn with_allow_http(self, allow_http: bool) -> Self

Sets what protocol is allowed. If allow_http is :

• false (default): Only HTTPS are allowed
• true: HTTP and HTTPS are allowed

pub fn with_allow_invalid_certificates(self, allow_insecure: bool) -> Self

Allows connections to invalid SSL certificates

• false (default): Only valid HTTPS certificates are allowed
• true: All HTTPS certificates are allowed

Warning

You should think very carefully before using this method. If invalid certificates are trusted, any certificate for any site will be trusted for use. This includes expired certificates. This introduces significant vulnerabilities, and should only be used as a last resort or for testing

pub fn with_http1_only(self) -> Self

Only use http1 connections

pub fn with_http2_only(self) -> Self

Only use http2 connections

pub fn with_proxy_url(self, proxy_url: impl Into<String>) -> Self

Set an HTTP proxy to use for requests

pub fn with_timeout(self, timeout: Duration) -> Self

Set a request timeout

The timeout is applied from when the request starts connecting until the response body has finished

pub fn with_connect_timeout(self, timeout: Duration) -> Self

Set a timeout for only the connect phase of a Client

pub fn with_pool_idle_timeout(self, timeout: Duration) -> Self

Set the pool max idle timeout

This is the length of time an idle connection will be kept alive

Default is 90 seconds

pub fn with_pool_max_idle_per_host(self, max: usize) -> Self

Set the maximum number of idle connections per host

Default is no limit

pub fn with_http2_keep_alive_interval(self, interval: Duration) -> Self

Sets an interval for HTTP2 Ping frames should be sent to keep a connection alive.

Default is disabled

pub fn with_http2_keep_alive_timeout(self, interval: Duration) -> Self

Sets a timeout for receiving an acknowledgement of the keep-alive ping.

If the ping is not acknowledged within the timeout, the connection will be closed. Does nothing if http2_keep_alive_interval is disabled.

Default is disabled

pub fn with_http2_keep_alive_while_idle(self) -> Self

Enable HTTP2 keep alive pings for idle connections

If disabled, keep-alive pings are only sent while there are open request/response streams. If enabled, pings are also sent when no streams are active

Default is disabled
