Warning
muhex requires a nightly version of the Rust compiler.
Muhex provides encoding and decoding in a hexadecimal representation, focusing on speed. It has zero dependencies (one optional, serde), compiles instantly and is faster.
Install the crate using the normal incantations:
cargo +nightly add muhexThen, you can use it as expected, and the interface is meant to mirror the one on the hex crate, like encoding:
println!("{}", muhex::encode("Hello world!")); // Prints "48656c6c6f20776f726c6421"And decoding:
println!("{}", muhex::decode("48656c6c6f20776f726c6421")?); // Prints "Hello world!"This is a benchmark on my own machine against the hex crate.

Please note that we can only achieve this performance because we only work on nightly Rust, and explicitly enforce SIMD. This is not a testament on the quality or performance of the hex crate. In fact, in most applications (if not all) will not benefit from any of those changes.
