Implementations on Foreign Types

impl SecretsReader for ExtendedUserMapping

fn load_credentials(self) -> Result<CredentialsLoading, Error>

Loads credentials for each [UserId] associated with a SystemUserId.

The SystemUserId of the mapping must be equal to the current system user calling this function. Relies on get_plaintext_secret_file and get_systemd_creds_secret_file to retrieve the specific path to a secret file for each [UserId] mapped to a SystemUserId.

Returns a CredentialsLoading, which may contain critical errors related to loading a passphrase for each available [UserId]. The caller is expected to handle any errors tracked in the returned object based on context.

Errors

Returns an error if

• the ExtendedUserMapping provides no SystemUserId,
• no system user equal to the SystemUserId exists,
• the SystemUserId is not equal to the currently calling system user,
• or the systemd-creds command is not available when trying to decrypt secrets.
