Struct CredentialsLoader

pub struct CredentialsLoader { /* private fields */ }

Credential loader for units.

Credentials are read by systemd on unit startup and exported by their ID.

Note: only the user associated with the unit and the superuser may access credentials.

let token = loader.get("token")?;
let token_metadata = token.metadata()?;
println!("token size: {}", token_metadata.len());

pub fn iter(&self) -> Result<ReadDir, SdError>
