Struct MetricRule 

#[non_exhaustive]
pub struct MetricRule {
    pub selector: String,
    pub metric_costs: HashMap<String, i64>,
    /* private fields */
}

Bind API methods to metrics. Binding a method to a metric causes that metric’s configured quota behaviors to apply to the method call.

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.

selector: String

Selects the methods to which this rule applies.

Refer to selector for syntax details.

metric_costs: HashMap<String, i64>

Metrics to update when the selected methods are called, and the associated cost applied to each metric.

The key of the map is the metric name, and the values are the amount increased for the metric against which the quota limits are defined. The value must not be negative.

Implementations

impl MetricRule

pub fn new() -> Self

pub fn set_selector<T: Into<String>>(self, v: T) -> Self

Sets the value of selector.

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

where T: IntoIterator<Item = (K, V)>, K: Into<String>, V: Into<i64>,

Sets the value of metric_costs.

Trait Implementations

impl Clone for MetricRule

fn clone(&self) -> MetricRule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetricRule

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

Formats the value using the given formatter.

impl Default for MetricRule

fn default() -> MetricRule

Returns the “default value” for a type.

impl Message for MetricRule

fn typename() -> &'static str

The typename of this message.

impl PartialEq for MetricRule

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