This crates provide two simple abstractions on low level atomic locks. The Spinlock and the Semaphore.
To use this crate simply add the dependency to your Cargo.toml file:
[dependencies]
ruspiro-lock = "0.1.0"
Once done the definition and usage of the locks is as follows:
Using a Spinlock to ensure exclusive access: ``` use ruspiro_lock::*;
static SPIN: Spinlock = Spinlock::new();
fn main() { SPIN.aquire(); // following code is only executed if the lock could be aquired, the executing core pause till then let _ = 10 + 3; SPIN.release(); } ```
Using a Semaphore to specify how often specific access is valid: ``` use ruspriro_lock::*;
static mut SEMA: Semaphore = Semaphore::new(1);
fn main() { unsafe { // unsafe necessary as accessing mut static's is unsafe if SEMA.trydown().isok() { // we gained access to the semaphore, do something let _ = 20 /4; SEMA.up(); } } } ```
