Struct BlockHash

pub struct BlockHash(/* private fields */);

A bitcoin block hash.

Implementations

impl BlockHash

pub const fn from_byte_array(bytes: <Hash as Hash>::Bytes) -> Self

Constructs a hash from the underlying byte array.

pub fn from_slice(sl: &[u8]) -> Result<BlockHash, FromSliceError>

👎Deprecated since 0.15.0: use from_byte_array instead

pub const fn to_byte_array(self) -> <Hash as Hash>::Bytes

Returns the underlying byte array.

pub const fn as_byte_array(&self) -> &<Hash as Hash>::Bytes

Returns a reference to the underlying byte array.

impl BlockHash
