crate.
sourcepub fn to_low_u64_be(&self) -> u64
pub fn to_low_u64_be(&self) -> u64

sourcepub fn to_low_u64_ne(&self) -> u64
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.
sourcepub fn from_low_u64_be(val: u64) -> Bloom
pub fn from_low_u64_be(val: u64) -> Bloom
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.
sourcepub fn from_low_u64_le(val: u64) -> Bloom
pub fn from_low_u64_le(val: u64) -> Bloom
Creates a new hash type from the given u64

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.
sourcepub fn from_low_u64_ne(val: u64) -> Bloom
pub fn from_low_u64_ne(val: u64) -> Bloom
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.
