mincache
Minimal crate to cache return values of your function returns.
Currently only supports a timer / cooldown cache.
Example
pub use mincache::timecache;
// "fmt" is what you'd put after core::time::Duration::from_<>. E.g. "secs", "millis", "nanos", etc.
#[timecache(time = 5000, fmt = "secs")]
pub fn xyz(x: i32) -> std::time::Instant {
println!("This will print once {x}");
// This value will be cloned each time this is called before the cooldown is over
// If you want to instead pass a reference, look into mincache/tests/ref.rs
// (just add ``reference = true`` to the attribute params)
std::time::Instant::now()
}
#[test]
fn main() {
// Will call the function a single time.
for _ in 0..1000000 {
let xyz = xyz(55);
}
}
