Enum PanicMode

pub enum PanicMode {
    Decrement,
    Poison,
}

What to do if a Barrier is destroyed during a panic.

Variants

Decrement

Nothing special.

Just decrement the number of expected threads, just like during any normal destruction.

Poison

Poison the barrier.

All calls to wait, including the ones that are already in progress, will panic too. Once poisoned, there’s no way to “unpoison” the barrier.

This is useful in case a failure in one thread makes the whole group unusable (very often in tests).

Trait Implementations

impl Clone for PanicMode

fn clone(&self) -> PanicMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PanicMode

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

Formats the value using the given formatter.

impl PartialEq for PanicMode

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