source · [−]

pub struct TryAcquireError { /* private fields */ }

Expand description

Error returned by Permit::try_acquire.

Implementations

source

impl TryAcquireError

source

pub fn is_closed(&self) -> bool

Returns true if the error was caused by a closed semaphore.

source

pub fn is_no_permits(&self) -> bool

Returns true if the error was caused by calling try_acquire on a semaphore with no available permits.
