Type Alias Counter

pub type Counter = GenericCounter<AtomicF64>;

Available on crate feature metrics only.

A Metric represents a single numerical value that only ever goes up.

Aliased Type

struct Counter { /* private fields */ }

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>

Panics

Panics in debug build if the value is < 0.

pub fn inc(&self)
