Abstraction for credential storage backends
Required Methods§
Sourcefn get_credential(&self, key: &str) -> Result<SecretString, CredentialError>
fn get_credential(&self, key: &str) -> Result<SecretString, CredentialError>
Retrieve a credential by key, returning a zeroing SecretString
Sourcefn available_keys(&self) -> Vec<String>
fn available_keys(&self) -> Vec<String>
List available credential keys.
May return an empty vec for security reasons (e.g. env-var providers avoid enumerating the process environment).
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
