Struct GenericCounter

pub struct GenericCounter<P>
where
    P: Atomic,
{ /* private fields */ }

The underlying implementation for Counter and IntCounter.

Implementations

impl<P> GenericCounter<P>

where P: Atomic,

pub fn new<S1, S2>(name: S1, help: S2) -> Result<GenericCounter<P>, Error>

where S1: Into<String>, S2: Into<String>,

Create a GenericCounter with the name and help arguments.

pub fn with_opts(opts: Opts) -> Result<GenericCounter<P>, Error>

Create a GenericCounter with the opts options.

pub fn inc_by(&self, v: <P as Atomic>::T)

Increase the given value to the counter.

Panics

Panics in debug build if the value is < 0.

pub fn inc(&self)

pub fn get(&self) -> <P as Atomic>::T

Return the counter value.

pub fn reset(&self)

pub fn local(&self) -> GenericLocalCounter<P>

Return a GenericLocalCounter for single thread usage.
