[−][src]Struct metrics::Key
A metric key.
A key always includes a name, but can optional include multiple labels used to further describe the metric.
Implementations
impl Key
[src]
pub fn from_name<N>(name: N) -> Self where
N: Into<ScopedString>,
[src]
N: Into<ScopedString>,
Creates a Key
from a name.
pub fn from_name_and_labels<N, L>(name: N, labels: L) -> Self where
N: Into<ScopedString>,
L: IntoLabels,
[src]
N: Into<ScopedString>,
L: IntoLabels,
Creates a Key
from a name and vector of Label
s.
pub fn name(&self) -> &ScopedString
[src]
Name of this key.
pub fn labels(&self) -> Option<Iter<Label>>
[src]
Labels of this key, if they exist.
pub fn map_name<F>(self, f: F) -> Self where
F: Fn(ScopedString) -> String,
[src]
F: Fn(ScopedString) -> String,
Map the name of this key to a new name, based on f
.
The value returned by f
becomes the new name of the key.
pub fn into_parts(self) -> (ScopedString, Option<Vec<Label>>)
[src]
Consumes this Key
, returning the name and any labels.
