pub enum UnminedTxId {
    Legacy(Hash),
    Witnessed(WtxId),
}
Expand description

A unique identifier for an unmined transaction, regardless of version.

“The transaction ID of a version 4 or earlier transaction is the SHA-256d hash of the transaction encoding in the pre-v5 format described above.

The transaction ID of a version 5 transaction is as defined in ZIP-244.

A v5 transaction also has a wtxid (used for example in the peer-to-peer protocol) as defined in ZIP-239.“ Spec: Transaction Identifiers

Variants

Legacy(Hash)

A legacy unmined transaction identifier.

Used to uniquely identify unmined version 1-4 transactions. (After v1-4 transactions are mined, they can be uniquely identified using the same Hash.)

Witnessed(WtxId)

A witnessed unmined transaction identifier.

Used to uniquely identify unmined version 5 transactions. (After v5 transactions are mined, they can be uniquely identified using only the Hash in their WtxId.id.)

For more details, see WtxId.

Implementations

Create a new UnminedTxId using a v1-v4 legacy transaction ID.

Correctness

This method must only be used for v1-v4 transaction IDs. Hash does not uniquely identify unmined v5 transactions.

Return the unique ID that will be used if this transaction gets mined into a block.

Correctness

For v1-v4 transactions, this method returns an ID which changes if this transaction’s effects (spends and outputs) change, or if its authorizing data changes (signatures, proofs, and scripts).

But for v5 transactions, this ID uniquely identifies the transaction’s effects.

Returns a mutable reference to the unique ID that will be used if this transaction gets mined into a block.

See Self::mined_id for details.

Return the digest of this transaction’s authorizing data, (signatures, proofs, and scripts), if it is a v5 transaction.

Returns a mutable reference to the digest of this transaction’s authorizing data, (signatures, proofs, and scripts), if it is a v5 transaction.
