Enum AddressExpiryError 

Source 
#[non_exhaustive]
pub enum AddressExpiryError {
    TimeExpired {
        expiry_time: u64,
    },
    HeightExpired {
        address_expiry: BlockHeight,
        chain_height: BlockHeight,
    },
    ExpiryHeightConflict {
        address_expiry: BlockHeight,

    },
}
Expand description

The ways in which a ZIP 316 Revision 2 recipient address’s expiry metadata can prevent a payment from being constructed.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

TimeExpired

The address’s expiry time is earlier than the current time.

Fields

§expiry_time: u64

The address’s expiry time, in seconds since the Unix epoch.

§

HeightExpired

The chain has advanced past the address’s expiry height.

Fields

§address_expiry: BlockHeight

The address’s expiry height.

§chain_height: BlockHeight

The height of the chain tip against which expiry was evaluated.

§

ExpiryHeightConflict

The transaction’s expiry height would exceed the address’s expiry height.

ZIP 316 forbids sending in this case rather than lowering the transaction’s expiry height to match, since an expiry height derived from the address’s metadata would leak information about the destination on chain.

Fields

§address_expiry: BlockHeight
§transaction_expiry: BlockHeight
§

TransactionExpiryDisabled

The address defines an expiry height, which requires the transaction to carry a nonzero expiry height, but transaction expiry was disabled.

Fields

§address_expiry: BlockHeight
