Enum MetricNamespaceScoping

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

Item scoping of metric namespaces.

This enum is used in ItemScoping to declare the contents of an item’s metric namespace.

Variants

None

This item does not contain metrics of any namespace. This should only be used for non-metric items.

Some(MetricNamespace)

This item contains metrics of a specific namespace.

Any

This item contains metrics of any namespace.

The namespace of metrics contained in this item is not known. This can be used to check rate limits or quotas of any namespace.

Implementations

impl MetricNamespaceScoping

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

Returns true if the given namespace matches the namespace of the item.

If the self is Any, this method returns true for 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.
