Struct Txid 

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

A bitcoin transaction hash/transaction ID.

For compatibility with the existing Bitcoin infrastructure and historical and current versions of the Bitcoin Core software itself, this and other sha256d::Hash types, are serialized in reverse byte order when converted to a hex string via std::fmt::Display trait operations.

See hashes::Hash::DISPLAY_BACKWARD for more details.

Implementations

impl Txid

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<Txid, FromSliceError>

👎Deprecated since 0.15.0: use from_byte_array instead

Copies a byte slice into a hash object.

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 Txid

pub const COINBASE_PREVOUT: Self

The Txid used in a coinbase prevout.

This is used as the “txid” of the dummy input of a coinbase transaction. This is not a real TXID and should not be used in any other contexts. See OutPoint::COINBASE_PREVOUT.
