Struct Device 

pub struct Device { /* private fields */ }

A Metal GPU with its command queue, kernel library and pipeline cache. Cheap to clone.

Implementations

impl Device

pub fn new_buffer(&self, len: usize) -> Result<Buffer>

A buffer of len bytes from the caching allocator. Its contents are unspecified (a reused buffer holds stale bytes); fails with GpuError::OutOfMemory beyond the memory limit.

pub fn buffer_from(&self, bytes: &[u8]) -> Result<Buffer>

A buffer holding a copy of bytes.

impl Device

pub fn command_buffer(&self) -> Result<CommandBuffer>

A new command buffer on this device’s queue.

impl Device

pub fn system_default() -> Option<Device>

The system’s default Metal device, or None if there is none (for example in some virtual machines).

pub fn shared() -> Option<&'static Device>

The process-wide default device, created on first use: one allocator, kernel cache and queue shared by everything that uses the GPU.

pub fn memory(&self) -> MemoryStats

Memory use and limits of this device’s allocator.

pub fn set_memory_limit(&self, bytes: usize) -> usize

Sets the memory limit (allocations beyond it fail) and returns the previous one.

pub fn set_cache_limit(&self, bytes: usize) -> usize

Sets the cache limit, trimming the cache to it, and returns the previous one.

pub fn clear_cache(&self)

Releases every cached buffer.

pub fn reset_peak(&self)

Resets the peak to the current active memory.

pub fn info(&self) -> &DeviceInfo

What this GPU is and can do.

pub fn pipeline(&self, name: &str) -> Result<Pipeline>

The compute pipeline for the kernel name from nuvec’s kernel library, compiled on first use and cached.

Trait Implementations

impl Clone for Device

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Device

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
