Rust implementation of the CRC-32-Castagnoli algorithm with hardware acceleration where possible.
Hardware accelleration on the following architectures:
1. x84-64 with SSE 4.2
* All stable versions of Rust
* If SSE 4.2 is enabled at compile time, it will only build the SSE implementation. Otherwise, the cpuid
is used to find the best implementation at runtime.
1. aarch64 with crc feature
* Only available on nightly (enabled by default without feature)
All other processors utilize a software fallback.
First, add this to your Cargo.toml
:
toml
[dependencies]
crc32c = "0.6"
```rust extern crate crc32c;
fn main() { let message = b"Hello world!"; let crc = crc32c::crc32c(message);
println!("hash = {}", crc);
} ```
