i24 v2 – 24-bit Signed Integer for Rust
Version 2.0 of i24, a 24-bit signed integer type for Rust is now available on crates.io. It is designed for use cases such as audio signal processing and embedded systems, where 24-bit precision has practical relevance.
About
i24 fills the gap between i16 and i32, offering:
- Efficient 24-bit signed integer representation
- Seamless conversion to and from
i32 - Basic arithmetic and bitwise operations
- Support for both little-endian and big-endian byte conversions
- Optional serde and pyo3 feature flags
Acknowledgements
Thanks to Vrtgs for major contributions including no_std support, trait improvements, and internal API cleanups. Thanks also to Oderjunkie for adding saturating_from_i32. Also thanks to everyone who commented on the initial post and gave feedback, it is all very much appreciated :)
Benchmarks
i24 mostly matches the performance of i32, with small differences across certain operations. Full details and benchmark methodology are available in the benchmark report.
Usage Example
use i24::i24;
fn main() {
let a = i24::from_i32(1000);
let b = i24::from_i32(2000);
let c = a + b;
assert_eq!(c.to_i32(), 3000);
}
