Macro secret 

secret!() { /* proc-macro */ }

Generate a new type for a secret

The secret! macro generates a new type for secrets such as passwords and API tokens. The type uses the secrecy crate internally to prevent accidentally leaking the inner value in debug or log statements.

The new type implements common traits like Display and From<&str> and From<String>. The inner value can be revealed using the expose method.

Example

use typed_fields::secret;

secret!(ApiToken);

let token: ApiToken = "super-secret-api-token".into();
let header = format!("Authorization: Bearer {}", token.expose());
