simoom_sys/lib.rs
1//! Operating-system layer of simoom: epoll, io_uring, kqueue, IOCP, sockets, SIMD scanning and
2//! hardware crypto intrinsics. This is the only simoom crate that contains `unsafe` code; every
3//! `unsafe` block carries a `// SAFETY:` comment.
4//!
5//! - [`net`]: owned non-blocking TCP and UDP sockets ([`net::Socket`]).
6//! - [`udp`]: batched datagram I/O with GRO/GSO, ECN and packet info.
7//! - [`driver`]: the completion-style I/O driver over epoll, io_uring, IOCP and kqueue, with a
8//! cross-thread [`driver::Waker`].
9//! - [`time`]: cheap monotonic clocks. [`cpu`]: CPU count and thread affinity.
10//! - [`alloc`]: a counting global allocator for memory measurements.
