Returns the chain's chain ID

Inserts a row into the `order_events` table only if the latest event for the corresponding order UID has a different label than the provided event.

The postgres database in our CI has different datetime precision than the `DateTime` uses. This leads to issues comparing round-tripped data. Work aro

Recovers the owner of the specified signature. This method returns an error if there is an issue recovering an ECDSA signature, or `None` for on-chai

Reduce the sell amount of this order by the given amount.

The id of the cached fast-path solution. Present only when the solution was successfully cached for a later `/settle`.

Set the solver fee.

Start a new proxy server with automatic failover between backends # Panics Panics if `backends` is empty. At least one backend URL is required.

Return the trades which fulfill non-liquidity auction orders. These are the orders placed by end users.

Clones self and returns an instance that captures metrics extended with the provided label.

Runs `body` with a freshly-started pool-indexer. The indexer is spawned before the closure runs, then `abort`ed and `await`ed after — so the port is f

This function adjusts quote amounts to directly compare them with the order's limits, ensuring a meaningful comparison for potential price improvement

Performs the specified GraphQL query on the current subgraph.

Returns the amount of time remaining to solve, or `None` if time's up.

Serves metrics on a dedicated server at the given address. Spawns a background task and returns its handle.
