Implementations§

Source§

impl DiversifierKey

Source

pub fn master(sk_m: &[u8]) -> Self

Source

pub fn from_bytes(key: [u8; 32]) -> Self

Constructs the diversifier key from its constituent bytes.

Source

pub fn as_bytes(&self) -> &[u8; 32]

Returns the byte representation of the diversifier key.

Source

pub fn diversifier(&self, j: DiversifierIndex) -> Option<Diversifier>

Attempts to produce a diversifier at the given index. Returns None if the index does not produce a valid diversifier.

Source

pub fn diversifier_index(&self, d: &Diversifier) -> DiversifierIndex

Returns the diversifier index to which this key maps the given diversifier.

This method cannot be used to verify whether the diversifier was originally generated with this diversifier key, because all valid diversifiers can be produced by all diversifier keys.

Source

pub fn find_diversifier( &self, j: DiversifierIndex, ) -> Option<(DiversifierIndex, Diversifier)>

Returns the first index starting from j that generates a valid diversifier, along with the corresponding diversifier. Returns None if the diversifier space contains no valid diversifiers at or above the specified diversifier index.
