eve.aio.splice

Async splice / zero-copy data transfer.

Provides async splice support on Linux using io_uring IORING_OP_SPLICE when available, falling back to the splice() syscall otherwise. On non-Linux platforms, operations fail with SpliceErrorReason.NOT_SUPPORTED.

At least one of the file descriptors must refer to a pipe.

Example (Linux):

import eve.aio.splice;

const available = AsyncSplice.ioUringSpliceAvailable();
// Use splice() via thread pool or io_uring depending on kernel support

struct AsyncSplice

Types 1

structAsyncSplice

Async splice helper for zero-copy data transfer.

On Linux, queries the kernel for IORING_OP_SPLICE support at runtime. When available, splice operations can be submitted through io_uring for fully asynchronous execution. Otherwise, the splice() syscall runs in a worker thread.

On non-Linux platforms, all operations return SpliceErrorReason.NOT_SUPPORTED.

Note

The current implementation provides the runtime probe only.

Actual async splice operations via io_uring are not yet implemented.

Methods

AsyncSplice create() static pure @safe nothrow @nogcCreate an async splice handle.

void dispose() @safe nothrow @nogcDispose the splice handle.

bool isOpen() @property const pure @safe nothrow @nogcWhether this handle is open for operations.
