Enum Exposure 

Source 
pub enum Exposure {
    Exposed {
        at_height: BlockHeight,
        gap_metadata: GapMetadata,
    },
    Unknown,
    CannotKnow,
}
Available on crate feature transparent-inputs only.
Expand description

Metadata describing whether and when a transparent address was exposed by the wallet.

Variants§

§

Exposed

The address has been exposed by the wallet.

Fields

§at_height: BlockHeight

The address was first exposed to the wider ecosystem at this height, to the best of our knowledge.

  • For user-generated addresses, this is the chain tip height at the time that the address was generated by an explicit request by the user or reserved for use in a ZIP 320 transaction. These heights are not recoverable from chain.
  • In the case of an address with its first use discovered in a transaction obtained by scanning the chain, this will be set to the mined height of that transaction. In recover from seed cases, this is what user-generated addresses will be assigned.
§gap_metadata: GapMetadata

Transparent address gap metadata, as of the time the query that produced this exposure metadata was executed.

§

Unknown

The address is not known to have been exposed to an external caller by the wallet.

The wallet makes its determination based on observed chain data and inference from standard wallet address generation patterns. In particular, this is the state that an address is in when it has been generated by the advancement of the transparent address gap. This judgement may be incorrect for restored wallets.

§

CannotKnow

It is not possible for the wallet to determine whether the address has been exposed, given the information the wallet has access to.
