Enum MetricNamespaceScoping

pub enum MetricNamespaceScoping {
    None,
    Some(MetricNamespace),
    Any,
}

Describes the metric namespace scoping of an item.

This enum is used within ItemScoping to represent the metric namespace of an item. It handles the different cases: no namespace, a specific namespace, or any namespace.

Variants

None

The item does not contain metrics of any namespace.

This should only be used for non-metric items.

Some(MetricNamespace)

The item contains metrics of a specific namespace.

Any

The item contains metrics of any namespace.

The specific namespace is not known or relevant. This can be used to check rate limits or quotas that should apply to any namespace.

Implementations

impl MetricNamespaceScoping

pub fn matches(&self, namespace: MetricNamespace) -> bool

Checks if the given namespace matches this namespace scoping.

Returns true in the following cases:

• If self is MetricNamespaceScoping::Some with the same namespace
• If self is MetricNamespaceScoping::Any, matching any namespace

Trait Implementations

impl Clone for MetricNamespaceScoping

fn clone(&self) -> MetricNamespaceScoping

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MetricNamespaceScoping

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

Formats the value using the given formatter.

impl Default for MetricNamespaceScoping

fn default() -> MetricNamespaceScoping

Returns the “default value” for a type.

impl From<MetricNamespace> for MetricNamespaceScoping

fn from(namespace: MetricNamespace) -> Self

Converts to this type from the input type.

impl Hash for MetricNamespaceScoping

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MetricNamespaceScoping

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

impl PartialOrd for MetricNamespaceScoping

fn partial_cmp(&self, other: &MetricNamespaceScoping) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
