Tuple Fields§

§0: [u8; 256]

Implementations§

Returns a new fixed hash where all bits are set to the given byte.

Returns a new zero-initialized fixed hash.

Returns the size of this hash in bytes.

Extracts a byte slice containing the entire fixed hash.

Extracts a mutable byte slice containing the entire fixed hash.

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

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

Returns the inner bytes array.

Returns a constant raw pointer to the value.

Returns a mutable raw pointer to the value.

Assign the bytes from the byte slice src to self.

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.

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

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.

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

Returns true if no bits are set.

Utilities using the byteorder crate.

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.

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.

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.

Note
  • The given u64 value is interpreted as little endian.

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.

Utilities using the rand crate.
