Struct DispatchAutoReleaseFrequency 

#[repr(transparent)]
pub struct DispatchAutoReleaseFrequency(pub c_ulong);

Values to pass to the dispatch_queue_attr_make_with_autorelease_frequency() function.

Dispatch queues with this autorelease frequency inherit the behavior from their target queue. This is the default behavior for manually created queues.

Dispatch queues with this autorelease frequency push and pop an autorelease pool around the execution of every block that was submitted to it asynchronously.

See: dispatch_queue_attr_make_with_autorelease_frequency().

Dispatch queues with this autorelease frequency never set up an individual autorelease pool around the execution of a block that is submitted to it asynchronously. This is the behavior of the global concurrent queues.

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool
