Implementations§

source§

impl ExpandedClueKey

source

pub fn new(clue_key: &ClueKey) -> Result<Self, Error>

source

pub fn create_clue_deterministic( &self, precision_bits: usize, rseed: [u8; 32] ) -> Result<Clue, Error>

Create a Clue intended for the DetectionKey corresponding to this clue key, deterministically, using the provided random seed.

The clue will be detected by the intended detection key with probability 1, and by other detection keys with probability 2^{-precision_bits}.

§Errors

precision_bits must be smaller than MAX_PRECISION.

source

pub fn create_clue<R: RngCore + CryptoRng>( &self, precision_bits: usize, rng: R ) -> Result<Clue, Error>

Create a Clue intended for the DetectionKey corresponding to this clue key.

The clue will be detected by the intended detection key with probability 1, and by other detection keys with probability 2^{-precision_bits}.

§Errors
