Struct secrecy::Secret

source ·
pub struct Secret<S>
where S: Zeroize,
{ /* private fields */ }
Expand description

Wrapper type for values that contains secrets, which attempts to limit accidental exposure and ensure secrets are wiped from memory when dropped. (e.g. passwords, cryptographic keys, access tokens or other credentials)

Access to the secret inner value occurs through the ExposeSecret trait, which provides an expose_secret() method for accessing the inner secret value.
