pub fn from_low_u64_be(val: u64) -> Self
[src]
Creates a new hash type from the given u64
value.
Note

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

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.
