pub struct Counter { /* private fields */ }

Expand description

A counter.

Implementations

source

impl Counter

source

pub fn noop() -> Self

Creates a no-op Counter which does nothing.

Suitable when a handle must be provided that does nothing i.e. a no-op recorder or a layer that disables specific metrics, and so on.

source

pub fn from_arc<F: CounterFn + Send + Sync + 'static>(a: Arc<F>) -> Self

Creates a Counter based on a shared handler.

source

pub fn increment(&self, value: u64)

Increments the counter.

source

pub fn absolute(&self, value: u64)

Sets the counter to an absolute value.

Mutably borrows from an owned value. Read more

source

impl<T> From<T> for T

const: unstable · source

fn from(t: T) -> T

Returns the argument unchanged.

source

impl<T, U> Into for T where
U: From<T>,

const: unstable · source

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

source

impl<T> ToOwned for T where
T: Clone,

type Owned = T

The resulting type after obtaining ownership.

source

fn to_owned(&self) -> T

Creates owned data from borrowed data, usually by cloning. Read more

source

fn clone_into(&self, target: &mut T)

🔬 This is a nightly-only experimental API. (toowned_clone_into)

Uses borrowed data to replace owned data, usually by cloning. Read more

source

impl<T, U> TryFrom for T where
U: Into<T>,

type Error = Infallible

The type returned in the event of a conversion error.

const: unstable · source

fn try_from(value: U) -> Result<T, <T as TryFrom>::Error>

Performs the conversion.

source

impl<T, U> TryInto for T where
U: TryFrom<T>,

type Error = >::Error

The type returned in the event of a conversion error.

const: unstable · source

fn try_into(self) -> Result<U, >::Error>

Performs the conversion.
