}

The 7 device ops the cache needs — nothing more. Implemented by the engine (and by any future backend); all ops are stream-ordered on the implementor’s worker stream.

Required Methods

fn zeros(&self, n: usize) -> Result<CudaSlice<f32>, Box<dyn Error>>

fn uninit(&self, n: usize) -> Result<CudaSlice<f32>, Box<dyn Error>>

fn alloc_u8(&self, n: usize) -> Result<CudaSlice<u8>, Box<dyn Error>>

fn htod_i32(&self, v: &[i32]) -> Result<CudaSlice<i32>, Box<dyn Error>>

fn clone_dtod( &self, src: &CudaSlice<f32>, ) -> Result<CudaSlice<f32>, Box<dyn Error>>

fn copy_into( &self, dst: &mut CudaSlice<f32>, off: usize, src: &CudaSlice<f32>, len: usize, ) -> Result<(), Box<dyn Error>>

fn set_i32_one( &self, d: &mut CudaSlice<i32>, v: i32, ) -> Result<(), Box<dyn Error>>

Dyn Compatibility

This trait is dyn compatible.

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

Implementors

impl KvDev for Engine

The memra-kv device seam (Phase D): the cache’s 7 ops delegate to the engine’s inherent methods (inherent methods win name resolution, so no recursion).
