pub struct Latch { /* fields omitted */ }

A lock for cooperative multitasking environment

Implementations

impl Latch[src]

pub fn new() -> Self[src]

Allocate and initialize the new latch.

pub fn lock(&self) -> LatchGuard<'_>[src]

Lock a latch. Waits indefinitely until the current fiber can gain access to the latch.

pub fn try_lock(&self) -> Option<LatchGuard<'_>>[src]

Try to lock a latch. Return immediately if the latch is locked.

Returns:

  • Some - success
  • None - the latch is locked.
