Struct SharedIncMetric 

Source 
pub struct SharedIncMetric(/* private fields */);
Expand description

Representation of a metric that is expected to be incremented from more than one thread, so more synchronization is necessary.

Implementations§

Source§

impl SharedIncMetric

Source

pub const fn new() -> Self

Const default construction.

Trait Implementations§

impl IncMetric for SharedIncMetric

Source§

fn add(&self, value: u64)

Source§

fn count(&self) -> u64

impl Serialize for SharedIncMetric

Source§

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>
