Enum Phase 

pub enum Phase {
    In,
    Out,
    End,
    Event,
}

Phase of an instrumented operation — lets a consumer correlate the inputs a call accepted with the data it produced.

Variants

In

Inputs accepted — the parameters that drive the operation.

Out

Output produced — the result data the operation returns.

End

A unit of work finished (use when there’s no separate in/out split).

Event

A point-in-time fact with no duration.

Trait Implementations

impl Clone for Phase

fn clone(&self) -> Phase

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Phase

impl Debug for Phase

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

Formats the value using the given formatter.

impl Eq for Phase

impl PartialEq for Phase

fn eq(&self, other: &Phase) -> 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.
