Enum google_api_proto::google::api::servicecontrol::v1::distribution::BucketOption

pub enum BucketOption {
    LinearBuckets(LinearBuckets),
    ExponentialBuckets(ExponentialBuckets),
    ExplicitBuckets(ExplicitBuckets),
}

Defines the buckets in the histogram. bucket_option and bucket_counts must be both set, or both unset.

Buckets are numbered in the range of [0, N], with a total of N+1 buckets. There must be at least two buckets (a single-bucket histogram gives no information that isn’t already provided by count).

The first bucket is the underflow bucket which has a lower bound of -inf. The last bucket is the overflow bucket which has an upper bound of +inf. All other buckets (if any) are called “finite” buckets because they have finite lower and upper bounds. As described below, there are three ways to define the finite buckets.

(1) Buckets with constant width. (2) Buckets with exponentially growing widths. (3) Buckets with arbitrary user-provided widths.

In all cases, the buckets cover the entire real number line (-inf, +inf). Bucket upper bounds are exclusive and lower bounds are inclusive. The upper bound of the underflow bucket is equal to the lower bound of the smallest finite bucket; the lower bound of the overflow bucket is equal to the upper bound of the largest finite bucket.

Variants

LinearBuckets(LinearBuckets)

Buckets with constant width.

ExponentialBuckets(ExponentialBuckets)

Buckets with exponentially growing width.

ExplicitBuckets(ExplicitBuckets)

Buckets with arbitrary user-provided width.

Implementations

impl BucketOption

pub fn encode<B>(&self, buf: &mut B)

where B: BufMut,

Encodes the message to a buffer.

pub fn merge<B>( field: &mut Option<BucketOption>, tag: u32, wire_type: WireType, buf: &mut B, ctx: DecodeContext ) -> Result<(), DecodeError>

where B: Buf,

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

pub fn encoded_len(&self) -> usize

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

Trait Implementations

impl Clone for BucketOption

fn clone(&self) -> BucketOption

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BucketOption

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

Formats the value using the given formatter.

impl PartialEq for BucketOption

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

This method tests for self and other values to be equal, and is used by ==.

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

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