A simple secret-keeping library for Rust.
secrecy is a simple, safe (i.e.
forbid(unsafe_code) library which
provides wrapper types and traits for secret management in Rust, namely the
Secret<T> type for wrapping another value in a "secret cell" which attempts
to limit exposure (only available through a special
This helps to ensure secrets aren't accidentally copied, logged, or otherwise exposed (as much as possible), and also ensures secrets are securely wiped from memory when dropped.

serde support for parsing owned secret values is available, gated

It uses the
DeserializeOwned traits to implement
deserializing secret types which also impl these traits.
This doesn't guarantee
