Expand description

A type that represents the recipient of a transaction output.

Variants vary along two independent axes:

  • Relationship to the wallet: whether the recipient address is Self::External to the wallet, an Self::EphemeralTransparent address of a wallet account (used transiently as a middle hop), or otherwise internal to a wallet account (recorded as Self::InternalShielded or Self::InternalTransparent, depending on payload domain).
  • Payload domain: whether the output is shielded (in which case what is recorded is the decrypted Note, since the recipient address is not itself externally meaningful) or transparent (in which case what is recorded is the on-chain-observable recipient address, since transparent outputs carry no analogous decryptable payload).

Variants§

§

External

An output sent to a recipient external to the wallet.

Fields

§recipient_address: ZcashAddress
§output_pool: PoolType
§

EphemeralTransparent

Available on crate feature transparent-inputs only.

A transparent output sent to an ephemeral address of a wallet account (e.g. the middle hop of a ZIP 320 / TEX flow). The outpoint is recorded so the wallet can later detect when this output is spent without relying on a continuous address watch.

Fields

§receiving_account: AccountId
§ephemeral_address: TransparentAddress
§outpoint: OutPoint
§

InternalTransparent

Available on crate feature transparent-inputs only.

A transparent output sent to a non-ephemeral transparent address belonging to a wallet account. Used to record the send side of a transparent output that the wallet both funded and received.

Distinct from Self::InternalShielded because for transparent outputs the recipient address is observable on chain and must be recorded; additionally, the receiving account may not be known at the point the send is recorded. For shielded outputs the recipient address is not externally meaningful, so wallet-internal sends are recorded against the receiving account alone.

Fields

§receiving_account: AccountId
§recipient_address: TransparentAddress
§

InternalShielded

A shielded output recorded against a wallet account. Used for same-account outputs such as change (external_address is None) and for outputs received via an external IVK but funded by another wallet account, in which case external_address is the address that was paid.

Fields

§receiving_account: AccountId
§external_address: Option<ZcashAddress>
§note: Box<Note>
