Struct ReimburseDbCache

pub struct ReimburseDbCache {
    pub db: Database,
    pub operator_xonly_pk: XOnlyPublicKey,
    pub deposit_outpoint: Option<OutPoint>,
    pub paramset: &'static ProtocolParamset,
    /* private fields */
}

Struct to retrieve and cache data from DB for creating TxHandlers on demand It can only store information for one deposit and operator pair. It has two context modes, for rounds or for deposits. Deposit context needs additional information, like the deposit outpoint, which is not needed for rounds. Round context can only create transactions that do not depend on the deposit, like the round tx and ready to reimburse tx. Deposit context can create all transactions. Note: This cache is specific to a single operator, for each operator a new cache is needed.

Fields

db: Database

operator_xonly_pk: XOnlyPublicKey

deposit_outpoint: Option<OutPoint>

paramset: &'static ProtocolParamset

Implementations

impl ReimburseDbCache

pub fn new_for_deposit( db: Database, operator_xonly_pk: XOnlyPublicKey, deposit_outpoint: OutPoint, paramset: &'static ProtocolParamset, ) -> Self

Creates a db cache that can be used to create txhandlers for a specific operator and deposit/kickoff

pub fn new_for_rounds( db: Database, operator_xonly_pk: XOnlyPublicKey, paramset: &'static ProtocolParamset, ) -> Self

Creates a db cache that can be used to create txhandlers for a specific operator and collateral chain

pub fn from_context(db: Database, context: &ContractContext) -> Self

Creates a db cache from a contract context. This context can possible include a deposit data, for which it will be equivalent to new_for_deposit, otherwise it will be equivalent to new_for_rounds.
