Note

The given bytes are interpreted in big endian order.

Panics

If the length of src and the number of bytes in self do not match.

pub fn from_slice(src: &[u8]) -> H512[src]

Create a new fixed-hash from the given slice src.

Panics

If the length of src and the number of bytes in Self do not match.

pub fn covers(&self, b: &H512) -> bool[src]

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

Returns true if no bits are set.

impl H512[src]

Utilities using the byteorder crate.

pub fn to_low_u64_be(&self) -> u64[src]

Returns the lowest 8 bytes interpreted as big-endian.

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.

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.

pub fn from_low_u64_be(val: u64) -> H512[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) -> H512[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) -> H512[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 H512[src]

Utilities using the rand crate.

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

    R: Rng + ?Sized
[src]

pub fn random() -> H512[src]

Create a new hash with cryptographically random content.
