Implementations

impl Did

pub fn in_range(&self, base_id: Self, a: Self, b: Self) -> bool

Test x <- (a, b)

pub fn bias(&self, did: Self) -> BiasId

Transform Did to BiasDid

pub fn rotate_affine(&self, scalar: u16) -> Vec<Did>

Rotate Transport did to a list of affined did affine x, n = [x + rotate(360/n)]

Methods from Deref<Target = H160>

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

Extracts a byte slice containing the entire fixed hash.

pub fn as_fixed_bytes(&self) -> &[u8; 20]

Extracts a reference to the byte array containing the entire fixed hash.

pub fn as_ptr(&self) -> *const u8

Returns a constant raw pointer to the value.

pub fn covers(&self, b: &H160) -> bool

Returns true if all bits set in b are also set in self.

pub fn is_zero(&self) -> bool

Returns true if no bits are set.

pub fn to_low_u64_be(&self) -> u64

Returns the lowest 8 bytes interpreted as little-endian.

Note

For hash type with less than 8 bytes the missing bytes are interpreted as being zero.

pub fn to_low_u64_ne(&self) -> u64

Returns the lowest 8 bytes interpreted as native-endian.

Note

For hash type with less than 8 bytes the missing bytes are interpreted as being zero.
