Shortens the vector to `new_len` elements, clearing all vacated storage slots. If `new_len` is greater than or equal to the current length, this has

Records that a previously-mined transaction is no longer onchain (e.g., after a reorg). If the hash was actually present and `mined_txs` becomes empt

Applies the provided [`DerivationStateUpdate`], returning an [`DerivationStateTransitionError`] if the state transition was invalid.

Add raw transactions into the [`SpanBatchTransactions`].

Sets `spender`'s allowance from `owner` to `amount`. Emits `Approval`.

Converts the [`AttributesWithParent`] into a deposits-only payload.

Assert helper: ensure the chosen VersionedValue has the expected block and deletion flag.

Asserts that `body` causes exactly `expected` increments on `storage.tx_acquisitions()`.

Returns the builder attributes.

Returns a mutable reference to the Swarm's behaviour.

Builds a new block with provided txs and timestamp

Build a test server with the full production middleware stack (`EthHealthCheckLayer` → `ProxyGetRequestLayer`) and the given RPC module. Pass `RpcMod

Builds a test genesis configuration programmatically. Creates a Base Sepolia-like genesis with: - All EVM and inherited rollup upgrades enabled from

Builds a consensus header and account proof response pair with a valid Merkle proof. The returned header's `state_root` is the trie root that the acco

Destroys `amount` tokens from `from`. Emits `Transfer(from, 0x0, amount)`.

Return the chain specification used by the harness.

Runs `validate` against a freshly-seeded nonce manager. `seed` may mutate the manager (e.g. advance a channel) before the (immutable) check.

Waits for generator capacity, then claims at most one proof job. This can wait while all generator permits are in use; use a cancellable `select!` wh

Clears OTEL-related environment variables that can interfere with CLI argument parsing. This is necessary because clap reads env vars for args with `e
