Module hex 

Tiny hex encoder used wherever a byte slice needs to be rendered as a hex string. Centralised so the same bytes.iter().map(|b| format!("{:02x}", b)).collect() doesn’t get re-typed across the crate.

Functions

to_hex

Encode bytes as a lowercase hex string.

to_hex_prefix

Encode the first n bytes (or fewer) as lowercase hex. Useful for short identifiers like bearer:<sha256-prefix> labels.
