This is a base16 (e.g. hexadecimal) encoding and decoding library which was initially written with an emphasis on performance.
This was before Rust added SIMD, and I haven't gotten around to adding that. It's still probably the fastest non-SIMD impl, but that doesn't say much.
Add base16 = "0.1" to Cargo.toml, then:
```rust extern crate base16;
fn main() { let originalmsg = "Foobar"; let hexstring = base16::encodelower(originalmsg); asserteq!(hexstring, "466f6f626172"); let decoded = base16::decode(&hexstring).unwrap(); asserteq!(String::fromutf8(decoded).unwrap(), originalmsg); } ```
More usage examples in the docs.
no_std UsageAs of 0.1.2, this crate by default has the std feature enabled, however, it
may be turned off, allowing it to be used in no_std envionments. Not all
functions are available without the stdlib, but each function should document whether or not it is.
Dual MIT/Apache2 (whichever you prefer) since that seems hip for Rust code.
