Expand description

An inventory hash which refers to some advertised or requested data.

Bitcoin calls this an “inventory vector” but it is just a typed hash, not a container, so we do not use that term to avoid confusion with Vec<T>.

Bitcoin reference

Variants

Error

An error.

The Bitcoin wiki just says “Any data of with this number may be ignored”, so we don’t include a typed hash.

Tx(Hash)

A hash of a transaction.

Block(Hash)

A hash of a block.

FilteredBlock(Hash)

A hash of a filtered block.

The Bitcoin wiki says: Hash of a block header, but only to be used in getdata message. Indicates the reply should be a merkleblock message rather than a block message; this only works if a bloom filter has been set.

Wtx(WtxId)

A pair with the hash of a V5 transaction and the Authorizing Data Commitment.

Introduced by ZIP-239, which is analogous to Bitcoin’s BIP-339.

Implementations

Creates a new inventory hash from a legacy transaction ID.

Correctness

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

Returns the block hash for this inventory hash, if this inventory hash is a non-filtered block variant.

Returns the unmined transaction ID for this inventory hash, if this inventory hash is a transaction variant.

Returns the serialized Zcash network protocol code for the current variant.
