A general surplus function. Can return different types of surplus based on the input parameters.

The buy amount for [`Side::Buy`] orders, or the sell amount for [`Side::Sell`] orders.

The calldata for this settlement.

`self + rhs`, `Overflow` when it does not fit.

Updates the orders that participated in settlements by incrementing their attempt count. `failure` indicates whether the settlement was successful or

A pool between "A" and "WETH".

Configures if verified price estimates should be ranked higher than unverified ones even if the price is worse. Per default verified quotes do not get

An example order which sells token "A" for token "D".

A pool between tokens "A" and "D".

A solution solving the [`ad_order`].

Returns the address of the Safe.

The `eth_call` response of an `aggregate3` whose sub-calls came back as given, in the order the reader asked for them.

All solutions including the ones that got filtered out.

Extracts the `appCode` from a full app-data document, if present. `appCode` sits at the document root, next to (not inside) the protocol `metadata`,

Returns the fee as a raw [`eth::U256`] value as it is represented on-chain.

Assembles a `QuoteCompetition` from every ranked estimate plus the competition-level context (native prices, gas price, expiration). Fails with [`Calc

Asserts `computed_rate` is within a `tolerance` of `expected_rate`.

Set specific auction ID which will be used during test. Setting auction ID can be used to test various scenarios when handling competing solutions in

Returns the order's available amounts to be passed to a solver engine. See [`Available`] for more details.

Returns the subset of `addresses` that are banned. Cache misses hit the configured remote sources.

The asset being bought, or [`eth::U256::one`] if this is a sell, to facilitate surplus.

Reads an entry without marking it as requested, so polling for a background update does not keep the entry alive.

POST the standard solve request and return the parsed response body.

Cancel a pending settlement by sending a transaction to self with a slightly higher gas price than the existing one.

Applies the needed DB modification to cancel a single order.

Function to check batching of many tokens

Token prices settled by this solution, expressed using an arbitrary reference unit chosen by the solver. These values are only meaningful in relation

The competition that runs auctions for this solver engine.

Computes the absolute tolerance amount from a relative factor.

Load the specified config file. Otherwise, a temporary config file will be created with reasonable values.

Verifies the run loop drains buffered updates and returns Ok when the sender drops. Event content is not asserted here: the persistence bodies are no-

Creates a cloneable stream that yields the current block whenever it changes. Uses websocket subscriptions for real-time block updates. The stream is

A solver client pointing at a dead endpoint (no listener).

Converts a `BigDecimal` amount in Ether units to wei.

Deploys onchain components with a solver and a trader, each funded with 100 ETH.
