Trace context propagation: associate the current span with the OTel trace of the given request, if any and valid.

Picks winners and sorts all solutions where winners come before non-winners and higher scores come before lower scores.

How old (in terms of blocks) a settlement should be, to be considered as a settlement from another environment. Currently set to ~6h

Whether the settlement contains interactions that could possibly revert on chain

Log a single mempool submission attempt. Called inline from the racing task so that errors from mempools that later get superseded are still visible i

Emit per-mempool race counters with the final, reclassified label (`Success` / `Revert` / `Expired` / `Other` / `Superseded` / `Disabled`). Called onc

Creates a vector with all possible combinations of the given solutions. The result is sorted descending by score.

Merges `new` into `existing` field by field. Returns [`MergeConflict`] if both overrides write the same field. Non-conflicting `state_diff` entries a

Recursively merge two TOML tables

Observe that two solutions were merged.

Unique addresses with a `Mint` or `Burn` in the chunk. We pre-load their `(tick, liquidity)` so the post-event liquidity can be derived from the in-ev

Observe that the API routes for a solver are being mounted.

Moves the checkpoint to the block `latest_block - MAX_REORG_BLOCK_COUNT`

Multiplies this fee by the given floating point number, rounding up.

Computes `x * q / d` rounding up. Returns `None` if `d` is `0` or if the result overflows a 256-bit integer.

Multiply the sell amount of this order by the given factor.

The symbol backfill writes `""` as a "tried and failed" sentinel. Surface that as missing instead of as an empty string.

All solutions that were not filtered out but also did not win.

Applies the normalization factor to a price.

In the DB we use `timestampz` which doesn't store nanoseconds, so we truncate them to make the comparison work.

The orders for the auction.

Returns the token in the pair which is not the one passed in, or None if token passed in is not part of the pair

Use the Uniswap constant AMM formula to calculate the output amount based on the input.

Extract the owner address from the order UID.

Calculates deterministic Uniswapv3 pool address. https://github.com/Uniswap/v3-periphery/blob/main/contracts/libraries/PoolAddress.sol

Parses dot-separated field paths into a set of paths.

Parse OrderCancellationError from HTTP response Flow: JSON -> orderbook::api::Error -> OrderCancellationError Note: Returns None for unknown error typ

Parse OrderReplacementError from HTTP response Flow: JSON -> orderbook::api::Error -> OrderReplacementError Note: Returns None for unknown error types

Parses the JSON body of the `/solve` request during the unified auction pre-processing since eagerly deserializing these requests is surprisingly cost

Returns the partial access list for a single trade, or `None` if the trade does not buy native ETH or its receiver has no on-chain code.

Returns possible path candidates with the specified number of maximum hops.

Does this order pay to a smart contract?
