Methods
impl Sha256dHash
[src]
pub fn as_ptr(&self) -> *const u8
[src]
Converts the object to a raw pointer
pub fn as_mut_ptr(&mut self) -> *mut u8
[src]
Converts the object to a mutable raw pointer
pub fn len(&self) -> usize
[src]
Returns the length of the object as an array
pub fn is_empty(&self) -> bool
[src]
Returns whether the object, as an array, is empty. Always false.
pub fn as_bytes(&self) -> &[u8; 32]
[src]
Returns the underlying bytes.
pub fn to_bytes(&self) -> [u8; 32]
[src]
Returns the underlying bytes.
pub fn into_bytes(self) -> [u8; 32]
[src]
Returns the underlying bytes.
impl Sha256dHash
[src]
pub fn from_data(data: &[u8]) -> Sha256dHash
[src]
Create a hash by hashing some data
pub fn into_le(self) -> Uint256
[src]
Converts a hash to a little-endian Uint256
pub fn into_be(self) -> Uint256

pub fn from_hex(s: &str) -> Result<Sha256dHash, HexError>
[src]
Decodes a big-endian (i.e. reversed vs sha256sum output) hex string as a Sha256dHash
pub fn into_hash64(self) -> Hash64
[src]
Converts a hash to a Hash64 by truncation
pub fn le_hex_string(&self) -> String
[src]
Human-readable hex output
