Struct BarrierWaitResult

pub struct BarrierWaitResult(bool);

Expand description

A BarrierWaitResult is returned by wait when all tasks in the Barrier have rendezvoused.

Tuple Fields§

§0: bool

Implementations§

impl BarrierWaitResult

pub fn is_leader(&self) -> bool

Returns true if this task from wait is the “leader task”.

Only one task will have true returned from their result, all other tasks will have false returned.
