impl H128[src]

Note

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

pub fn to_low_u64_le(&self) -> u64[src]

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 from_low_u64_be(val: u64) -> Self[src]

Creates a new hash type from the given u64 value.

Note

  • The given u64 value is interpreted as big endian.
  • Ignores the most significant bits of the given value if the hash type has less than 8 bytes.

pub fn from_low_u64_le(val: u64) -> Self[src]

Creates a new hash type from the given u64 value.

Note

  • The given u64 value is interpreted as little endian.
  • Ignores the most significant bits of the given value if the hash type has less than 8 bytes.

pub fn from_low_u64_ne(val: u64) -> Self[src]

Creates a new hash type from the given u64 value.

Note

  • The given u64 value is interpreted as native endian.
  • Ignores the most significant bits of the given value if the hash type has less than 8 bytes.

impl H128[src]

Utilities using the rand crate.

pub fn randomize_using<R: ?Sized>(&mut self, rng: &mut R) where
    R: Rng
[src]

Assign self to a cryptographically random value using the given random number generator.

pub fn randomize(&mut self)[src]

pub fn random_using<R: ?Sized>(rng: &mut R) -> Self where
    R: Rng
[src]

pub fn random() -> Self[src]

Create a new hash with cryptographically random content.
