Struct WiFiRSSISource 

pub struct WiFiRSSISource;

Entropy source that harvests WiFi RSSI and noise floor fluctuations.

On macOS, it attempts multiple methods to read the current RSSI:

1. networksetup -listallhardwareports to discover the Wi-Fi device name, then ipconfig getsummary <device> to read RSSI/noise.
2. Fallback: the airport -I command from Apple’s private framework.

The raw entropy is a combination of RSSI LSBs, successive RSSI deltas, noise floor LSBs, and measurement timing jitter.

No tunable parameters — automatically discovers the Wi-Fi device and selects the best available measurement method.

Implementations

impl WiFiRSSISource

pub fn new() -> Self

Trait Implementations

impl Default for WiFiRSSISource

fn default() -> Self

Returns the “default value” for a type.

impl EntropySource for WiFiRSSISource

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.

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.
