Implementations§

source§

impl Buffer

source

pub(crate) fn raw<'a>( &'a self, guard: &'a SnatchGuard<'_>, ) -> Option<&'a dyn DynBuffer>

source

pub(crate) fn try_raw<'a>( &'a self, guard: &'a SnatchGuard<'_>, ) -> Result<&'a dyn DynBuffer, DestroyedResourceError>

source

pub(crate) fn check_destroyed<'a>( &'a self, guard: &'a SnatchGuard<'_>, ) -> Result<(), DestroyedResourceError>

source

pub(crate) fn check_usage( &self, expected: BufferUsages, ) -> Result<(), MissingBufferUsageError>

Checks that the given buffer usage contains the required buffer usage, returns an error otherwise.

source

pub(crate) fn map_async( self: &Arc<Self>, offset: BufferAddress, size: Option<BufferAddress>, op: BufferMapOperation, ) -> Result<SubmissionIndex, (BufferMapOperation, BufferAccessError)>

Returns the mapping callback in case of error so that the callback can be fired outside of the locks that are held in this function.

source

pub(crate) fn map( &self, snatch_guard: &SnatchGuard<'_>, ) -> Option<BufferMapPendingClosure>

This function returns None only if Self::map_state is not BufferMapState::Waiting.

source

pub(crate) fn unmap(self: &Arc<Self>) -> Result<(), BufferAccessError>

source

fn unmap_inner( self: &Arc<Self>, ) -> Result<Option<BufferMapPendingClosure>, BufferAccessError>

source

pub(crate) fn destroy(self: &Arc<Self>) -> Result<(), DestroyError>
