IncomingMatching

Fund a crossing arrival, match it in memory, then index only its remainder.

Active LP pools retain the existing storage path. Pending orders cannot match before funding.

Constants

STAGE

bytes32 private constant STAGE = keccak256("asyncswap.incoming.record");

POOL

bytes32 private constant POOL = keccak256("asyncswap.incoming.pool");

ID

bytes32 private constant ID = keccak256("asyncswap.incoming.id");

Functions

pending

function pending(PoolId poolId) public view returns (bool result);

Parameters

Name	Type	Description
poolId	`PoolId`

Returns

Name	Type	Description
result	`bool`

addOrder

Shared stored-admission wrapper. Keeping it here avoids duplicating admission bytecode in AsyncMatching, which only needs reductions and settlement for existing orders.

function addOrder(AsyncFiller.State storage self, AsyncFiller.Book storage book, AsyncFiller.NewOrder memory order)
        public;

Parameters

Name	Type	Description
self	`AsyncFiller.State`
book	`AsyncFiller.Book`
order	`AsyncFiller.NewOrder`

stage

function stage(AsyncFiller.State storage self, AsyncFiller.Book storage book, AsyncFiller.NewOrder memory order)
        public;

Parameters

Name	Type	Description
self	`AsyncFiller.State`
book	`AsyncFiller.Book`
order	`AsyncFiller.NewOrder`

_canCross

Resting-only arrivals keep ordinary admission. The memory bridge pays off when an opposite order crosses; repeat full selection after funding because callbacks can reprice.

function _canCross(AsyncFiller.Book storage book, AsyncFiller.NewOrder memory order) private view returns (bool);

Parameters

Name	Type	Description
book	`AsyncFiller.Book`
order	`AsyncFiller.NewOrder`

Returns

Name	Type	Description
<none>	`bool`

matchNewOrder

Delegatecall keeps escrow and the LP self-call in the hook context, while moving venue orchestration out of the hook's size-constrained runtime. Funding/auth stay in the Router/hook.

function matchNewOrder(
        AsyncFiller.State storage self,
        AsyncFiller.Book storage book,
        AsyncOrder calldata order,
        bytes32 id
    ) public returns (uint8 matched);

Parameters

Name	Type	Description
self	`AsyncFiller.State`
book	`AsyncFiller.Book`
order	`AsyncOrder`
id	`bytes32`

Returns

Name	Type	Description
matched	`uint8`

_poolBeatsBook

The pool goes first only while its adjusted price beats the best opposite level. An equal level or empty opposite side leaves the book first; the existing LP limit is unchanged.

function _poolBeatsBook(
        AsyncFiller.State storage self,
        AsyncFiller.Book storage book,
        PoolKey calldata key,
        bool isBuy
    ) private view returns (bool, uint160);

Parameters

Name	Type	Description
self	`AsyncFiller.State`
book	`AsyncFiller.Book`
key	`PoolKey`
isBuy	`bool`

Returns

Name	Type	Description
<none>	`bool`
<none>	`uint160`

_matchPending

function _matchPending(
        AsyncFiller.State storage self,
        AsyncFiller.Book storage book,
        PoolKey calldata key,
        bytes32 id,
        address owner
    ) private returns (bool handled, uint8 matched);

Parameters

Name	Type	Description
self	`AsyncFiller.State`
book	`AsyncFiller.Book`
key	`PoolKey`
id	`bytes32`
owner	`address`

Returns

Name	Type	Description
handled	`bool`
matched	`uint8`

_load

function _load(bytes32 id, address owner) private returns (AsyncFiller.OrderInfo memory incoming);
