pub struct H256(pub [u8; 32]);
Expand description
Fixed-size uninterpreted hash type with 32 bytes (256 bits) size.
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
.
The given bytes are interpreted in big endian order.
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
.
The given bytes are interpreted in big endian order.
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.
