Enum Backend 

pub enum Backend {
    Auto,
    Epoll,
    IoUring,
    Iocp,
    Kqueue,
}

Which I/O back end a driver uses.

Variants

Auto

Pick for this OS: epoll on Linux (io_uring when SIMOOM_BACKEND=io_uring is set), IOCP on Windows, kqueue on macOS and BSD.

Epoll

Linux epoll, edge-triggered.

IoUring

Linux io_uring (6.1+). Falls back to epoll when the kernel refuses it.

Iocp

Windows I/O completion ports.

Kqueue

macOS and BSD kqueue.

Implementations

impl Backend

pub fn resolve(self) -> Backend

The back end Auto resolves to on this OS, honouring SIMOOM_BACKEND (epoll, io_uring/uring, iocp, kqueue).

pub fn name(self) -> &'static str

A short lower-case name.
