Struct RateLimitInfo

pub struct RateLimitInfo {
    pub period: Option<Duration>,
    pub factor: f64,
}

Information about how client should adjust the load to Bigtable.

Fields

period: Option<Duration>

Time that clients should wait before adjusting the target rate again. If clients adjust rate too frequently, the impact of the previous adjustment may not have been taken into account and may over-throttle or under-throttle. If clients adjust rate too slowly, they will not be responsive to load changes on server side, and may over-throttle or under-throttle.

factor: f64

If it has been at least one period since the last load adjustment, the client should multiply the current load by this value to get the new target load. For example, if the current load is 100 and factor is 0.8, the new target load should be 80. After adjusting, the client should ignore factor until another period has passed.

The client can measure its load using any unit that’s comparable over time For example, QPS can be used as long as each request involves a similar amount of work.

Trait Implementations

Formats the value using the given formatter.

impl Default for RateLimitInfo

fn default() -> Self

Returns the “default value” for a type.

impl Message for RateLimitInfo

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>

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,

impl PartialEq for RateLimitInfo

fn eq(&self, other: &RateLimitInfo) -> 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.
