Struct Interest 

pub struct Interest(/* private fields */);

What an Observer asks for: a set of flags. | and |= unite two sets, union does in a const, and contains tests one.

use dataflow_rs::observe::Interest;

const TIMED_TASKS: Interest = Interest::TASKS.union(Interest::TIMINGS);
assert_eq!(TIMED_TASKS, Interest::TASKS | Interest::TIMINGS);

Every observer receives RunStarted and RunFinished.

Implementations

impl Interest

pub const NONE: Self

No flag: the run’s events only.

pub const WORKFLOWS: Self

WorkflowStarted and WorkflowFinished.

pub const TASKS: Self

TaskFinished.

pub const TIMINGS: Self

Each elapsed this observer is given is Some: the clock is read.

pub const ALL: Self

Every flag.

pub const fn union(self, other: Self) -> Self

The flags of either set: |, usable in a const.

pub const fn contains(self, other: Self) -> bool

Whether every flag of other is in this set: always for NONE.

pub const fn is_empty(self) -> bool

Whether the set holds no flag.
