    type Unpark: Unpark;
    type Error;
    fn unpark(&self) -> Self::Unpark;

Error returned by park

Required Methods

`fn unpark(&self) -> Self::Unpark`

Get a new Unpark handle associated with this Park instance.

`fn park(&mut self) -> Result<(), Self::Error>`

Block the current thread unless or until the token is available.

A call to park does not guarantee that the thread will remain blocked forever, and callers should be prepared for this possibility. This function may wakeup spuriously for any reason.

See module documentation for more details.

Panics

This function should not panic, but ultimiately, panics are left as an implementation detail. Refer to the documentation for the specific Park implementation

`fn park_timeout(&mut self, duration: Duration) -> Result<(), Self::Error>`

Park the current thread for at most duration.

This function is the same as park but allows specifying a maximum time to block the thread for.

Same as park, there is no guarantee that the thread will remain blocked for any amount of time. Spurious wakeups are permitted for any reason.

See module documentation for more details.

Panics

This function should not panic, but ultimiately, panics are left as an implementation detail. Refer to the documentation for the specific Park implementation
