Crate baracuda_cufile_sys 

Raw FFI + dynamic loader for NVIDIA cuFile (GPUDirect Storage).

Linux-only: cuFile calls ibverbs + NVIDIA’s GDS kernel driver and has no Windows/macOS analogue. On non-Linux platforms the loader returns LoaderError::UnsupportedPlatform.

Modules

CUfileOpcode

Opcode selector for CUfileIOParams_t.

Structs

CUfileDescr_t

CUfileDescr_t — struct describing a file (Unix fd or Win32 handle) for registration. cuFile’s own layout is an outer tagged union; we model only the Unix-fd path since this API is Linux-only anyway.

CUfileError_t

CUfileError_t — status plus a CUDA error code (for I/O that dispatched through the GPU).

CUfileIOEvents_t

CUfileIOEvents_t — status for a single batched-I/O entry.

CUfileIOParams_t

CUfileIOParams_t — 1 entry in a batched-IO request.

CUfileOpError

cuFile operation status (a.k.a. CUfileOpError).

CUfileBatchHandle_t
