Implementations

impl PerfMetric

pub const fn name(&self) -> &'static str

Returns the name of this metric as it appears in RocksDB C++

Trait Implementations

impl Clone for PerfMetric

fn clone(&self) -> PerfMetric

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for PerfMetric

impl Debug for PerfMetric

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for PerfMetric

impl PartialEq for PerfMetric

fn eq(&self, other: &PerfMetric) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StructuralPartialEq for PerfMetric
