Shared memory crate designed for simplicity, safety, and extensibility. With minimal dependencies on libc and tracing, this crate wraps unsafe shared memory operations in a user-friendly API.

Features:

• Simple API: Offers an easy-to-use interface for shared memory operations, abstracting libc complexities.
• Clear Error Handling: Distinguishes between Clean and Dirty system errors.
• Built-in Synchronization: Includes a semaphore-based lock for safe shared memory access.
• Extendable: Flexibility to implement custom synchronization logic through the CortexSync trait.

Simple example using the built-in semaphore lock

// Creating a segment of shared memory
let key = 123;
let data: f64 = 42.0;
let cortex_1: Cortex<_, Semaphore> = Cortex::new(key, data, None).unwrap();
assert_eq!(cortex_1.read(), 42.0);

// Attaching to an existing segment of shared memory (using an existing key)
let cortex_2: Cortex<f64, Semaphore> = Cortex::attach(key).unwrap();
assert_eq!(cortex_1.read(), cortex_2.read());
