An exclusive view of locally staged native submissions.

Required Associated Types

type Owned

type Vacancy: Vacancy<'q, T, Owned = Self::Owned>

type Reserved<const N: usize>: Chain<T, N>

type Prepared<'e, E: 'e, const N: usize>: Ready

Required Methods

fn refresh(&mut self)

fn len(&self) -> U32<0, { u32::MAX }>

fn is_empty(&self) -> bool

fn try_one(self) -> Result<Self::Vacancy, Full>

fn try_acquire(self) -> Result<Self::Vacancy, Full>

Acquires the current kernel head without publishing local submissions. A full queue leaves both cached and shared queue state unchanged.

fn try_reserve<const N: usize>( self, count: Limit<N>, ) -> Result<Self::Reserved<N>, Full>

fn prepare<'e, const N: usize>( self, entries: &'e [Self::Owned; N], ) -> Result<Self::Prepared<'e, Self::Owned, N>, Full>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
