    fn config_options(&self) -> Vec<(&'static str, String)> { ... }
}

Trait that every entropy source must implement.

Required Methods

fn info(&self) -> &SourceInfo

Source metadata.

fn is_available(&self) -> bool

Check if this source can operate on the current machine.

fn collect(&self, n_samples: usize) -> Vec<u8>

Collect raw entropy samples. Returns a Vec<u8> of up to n_samples bytes.

Provided Methods

fn name(&self) -> &'static str

Convenience: name from info.

fn set_config(&self, _key: &str, _value: &str) -> Result<(), String>

Optional runtime configuration. Returns Err if unsupported.

fn config_options(&self) -> Vec<(&'static str, String)>

List configurable keys and their current values.
