Struct TrafficSplit 

#[non_exhaustive]
pub struct TrafficSplit {
    pub shard_by: ShardBy,
    pub allocations: HashMap<String, f64>,
    /* private fields */
}

Traffic routing configuration for versions within a single service. Traffic splits define how traffic directed to the service is assigned to versions.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

shard_by: ShardBy

Mechanism used to determine which version a request is sent to. The traffic selection algorithm will be stable for either type until allocations are changed.

allocations: HashMap<String, f64>

Mapping from version IDs within the service to fractional (0.000, 1] allocations of traffic for that version. Each version can be specified only once, but some versions in the service may not have any traffic allocation. Services that have traffic allocated cannot be deleted until either the service is deleted or their traffic allocation is removed. Allocations must sum to 1. Up to two decimal place precision is supported for IP-based splits and up to three decimal places is supported for cookie-based splits.

Implementations

impl TrafficSplit

pub fn new() -> Self

Creates a new default instance.

pub fn set_shard_by<T: Into<ShardBy>>(self, v: T) -> Self

Sets the value of shard_by.

Example

use google_cloud_appengine_v1::model::traffic_split::ShardBy;
let x0 = TrafficSplit::new().set_shard_by(ShardBy::Cookie);
let x1 = TrafficSplit::new().set_shard_by(ShardBy::Ip);
let x2 = TrafficSplit::new().set_shard_by(ShardBy::Random);

pub fn set_allocations<T, K, V>(self, v: T) -> Self

where T: IntoIterator<Item = (K, V)>, K: Into<String>, V: Into<f64>,

Sets the value of allocations.

Example

let x = TrafficSplit::new().set_allocations([
    ("key0", 123.5),
    ("key1", 456.5),
]);

Trait Implementations

impl Clone for TrafficSplit

fn clone(&self) -> TrafficSplit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TrafficSplit

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

Formats the value using the given formatter.

impl Default for TrafficSplit

fn default() -> TrafficSplit

Returns the “default value” for a type.

impl Message for TrafficSplit

fn typename() -> &'static str

The typename of this message.

impl PartialEq for TrafficSplit

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