hex

Hexadecimal encoding and decoding with typed errors.

Decoding accepts either case and rejects anything that is not pairs of hex digits, so trim whitespace and strip 0x prefixes before calling it.

Install

Cargo feature hex (enabled by default). To compile only this module:

cargo add helpers4 --no-default-features --features hex

or in Cargo.toml:

[dependencies]
helpers4 = { version = "0.0.5", default-features = false, features = ["hex"] }

Import path: helpers4::hex.
