device: Retained<ProtocolObject<dyn MTLDevice>>

queue: Retained<ProtocolObject<dyn MTLCommandQueue>>

Implementations

impl MetalContext

pub fn new() -> Result<Self>

pub fn compile_library( &self, source: &str, ) -> Result<Retained<ProtocolObject<dyn MTLLibrary>>>

pub fn pipeline( &self, library: &ProtocolObject<dyn MTLLibrary>, function: &str, ) -> Result<Retained<ProtocolObject<dyn MTLComputePipelineState>>>

pub unsafe fn wrap_mmap( &self, bytes: &[u8], ) -> Result<Retained<ProtocolObject<dyn MTLBuffer>>>

Expose an existing mapping as a Metal buffer without copying it.

Safety

The page-rounded region must remain mapped until this buffer and all GPU work using it are finished. The caller must synchronize CPU writes with GPU access; the buffer does not own the mapping.

pub unsafe fn wrap_region( &self, ptr: *mut u8, len: usize, ) -> Result<Retained<ProtocolObject<dyn MTLBuffer>>>

Wrap a page-aligned portion of a mapping owned by the expert pool.

Safety

ptr..ptr+len must remain mapped for the buffer’s lifetime and all submitted GPU work. CPU/GPU access must obey the pool’s event handshake, including outstanding reads before a slot is reused.

fn check_allocation(&self, len: usize) -> Result<()>

pub fn new_buffer( &self, len: usize, ) -> Result<Retained<ProtocolObject<dyn MTLBuffer>>>

pub fn throttle_probe(&self) -> Result<f64>
