Struct FeatureFlags

pub struct FeatureFlags {
    pub reverse_scans: bool,
    pub mutate_rows_rate_limit: bool,
    pub mutate_rows_rate_limit2: bool,
    pub last_scanned_row_responses: bool,
    pub routing_cookie: bool,
    pub retry_info: bool,
    pub client_side_metrics_enabled: bool,
    pub traffic_director_enabled: bool,
    pub direct_access_requested: bool,
}

Feature flags supported or enabled by a client. This is intended to be sent as part of request metadata to assure the server that certain behaviors are safe to enable. This proto is meant to be serialized and websafe-base64 encoded under the bigtable-features metadata key. The value will remain constant for the lifetime of a client and due to HTTP2’s HPACK compression, the request overhead will be tiny. This is an internal implementation detail and should not be used by end users directly.

Fields

reverse_scans: bool

Notify the server that the client supports reverse scans. The server will reject ReadRowsRequests with the reverse bit set when this is absent.

mutate_rows_rate_limit: bool

Notify the server that the client enables batch write flow control by requesting RateLimitInfo from MutateRowsResponse. Due to technical reasons, this disables partial retries.

mutate_rows_rate_limit2: bool

Notify the server that the client enables batch write flow control by requesting RateLimitInfo from MutateRowsResponse. With partial retries enabled.

last_scanned_row_responses: bool

Notify the server that the client supports the last_scanned_row field in ReadRowsResponse for long-running scans.

routing_cookie: bool

Notify the server that the client supports using encoded routing cookie strings to retry requests with.

retry_info: bool

Notify the server that the client supports using retry info back off durations to retry requests with.

client_side_metrics_enabled: bool

Notify the server that the client has client side metrics enabled.

traffic_director_enabled: bool

Notify the server that the client using Traffic Director endpoint.

direct_access_requested: bool

Notify the server that the client explicitly opted in for Direct Access.

Trait Implementations

impl Clone for FeatureFlags

fn clone(&self) -> FeatureFlags

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FeatureFlags

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FeatureFlags

fn default() -> Self

Returns the “default value” for a type.

impl Message for FeatureFlags

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for FeatureFlags

fn eq(&self, other: &FeatureFlags) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
