Struct DNSTimingSource 

pub struct DNSTimingSource { /* private fields */ }

Entropy source that measures the round-trip time of DNS A-record queries sent to public resolvers. Timing jitter in the nanosecond range is harvested as raw entropy.

No tunable parameters — cycles through a fixed set of public DNS servers and hostnames automatically.

Implementations

impl DNSTimingSource

pub fn new() -> Self

Trait Implementations

impl Default for DNSTimingSource

fn default() -> Self

Returns the “default value” for a type.

impl EntropySource for DNSTimingSource

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.
