Crate lowlet 

Low-latency inter-process communication library.

This crate provides high-performance primitives for IPC using shared memory and lock-free data structures. Designed for latency-critical applications such as trading systems and real-time processing.

Modules

• shm - Shared memory region management
• sync - Synchronization primitives (spinlocks, barriers, fences)
• lf - Lock-free data structures (queues, stacks)
• buf - Ring buffer implementations
• chan - Channel abstraction for message passing

Example

use lowlet::channel;

let (tx, rx) = channel::<u64, 1024>();
tx.send(42).unwrap();
let value = rx.recv().unwrap();

Safety

This crate uses inline assembly for x86_64 atomics and direct system calls for shared memory. All unsafe code is carefully reviewed for correctness.

Re-exports

pub use chan::Receiver;
