debug API implementation.

This type provides the functionality for handling debug related requests.

Implementations

impl<Eth> DebugApi<Eth>

where Eth: RpcNodeCore,

pub fn new( eth_api: Eth, blocking_task_guard: BlockingTaskGuard, executor: &Runtime, stream: impl Stream<Item = ConsensusEngineEvent<<Eth as RpcNodeCore>::Primitives>> + Send + Unpin + 'static, ) -> DebugApi<Eth>

Create a new instance of the DebugApi

pub fn eth_api(&self) -> &Eth

Access the underlying Eth API.

pub fn provider(&self) -> &<Eth as RpcNodeCore>::Provider

Access the underlying provider.

impl<Eth> DebugApi<Eth>

where Eth: TraceExt,

pub async fn debug_trace_raw_block( &self, rlp_block: Bytes, opts: GethDebugTracingOptions, ) -> Result<Vec<TraceResult<GethTrace, String>>, <Eth as EthApiTypes>::Error>

Replays the given block and returns the trace of each transaction.

This expects a rlp encoded block

Note, the parent of this block must be present, or it will fail.

The block is supplied by the caller, so its replay is bounded by a timeout of 30 seconds: no transaction starts after it expires, the request then fails with EthApiError::ExecutionTimedOut. The replay retains its tracing permit until the running transaction finishes.

pub async fn debug_trace_block( &self, block_id: BlockId, opts: GethDebugTracingOptions, ) -> Result<Vec<TraceResult<GethTrace, String>>, <Eth as EthApiTypes>::Error>

Replays a block and returns the trace of each transaction.

pub async fn debug_trace_transaction( &self, tx_hash: FixedBytes<32>, opts: GethDebugTracingOptions, ) -> Result<GethTrace, <Eth as EthApiTypes>::Error>

Trace the transaction according to the provided options.

Ref: https://geth.ethereum.org/docs/developers/evm-tracing/built-in-tracers

pub async fn debug_trace_call( &self, call: <<Eth as EthApiTypes>::NetworkTypes as RpcTypes>::TransactionRequest, block_id: Option<BlockId>, opts: GethDebugTracingCallOptions, ) -> Result<GethTrace, <Eth as EthApiTypes>::Error>

The debug_traceCall method lets you run an eth_call within the context of the given block execution using the final state of parent block as the base.

If tx_index is provided in opts, the call will be traced at the state after executing transactions up to the specified index within the block (0-indexed). If not provided, then uses the post-state (default behavior).

Differences compare to eth_call:

• debug_traceCall executes with enabled basefee check, eth_call does not: https://github.com/paradigmxyz/reth/issues/6240

pub async fn debug_trace_call_many( &self, bundles: Vec<Bundle<<<Eth as EthApiTypes>::NetworkTypes as RpcTypes>::TransactionRequest>>, state_context: Option<StateContext>, opts: Option<GethDebugTracingCallOptions>, ) -> Result<Vec<Vec<GethTrace>>, <Eth as EthApiTypes>::Error>

The debug_traceCallMany method lets you run an eth_callMany within the context of the given block execution using the first n transactions in the given block as base. Each following bundle increments block number by 1 and block timestamp by 12 seconds

pub async fn debug_execution_witness_by_block_hash( &self, hash: FixedBytes<32>, mode: Option<ExecutionWitnessMode>, ) -> Result<ExecutionWitness, <Eth as EthApiTypes>::Error>

Generates an execution witness for the given block hash. see Self::debug_execution_witness for more info.

pub async fn debug_execution_witness( &self, block_id: BlockId, mode: Option<ExecutionWitnessMode>, ) -> Result<ExecutionWitness, <Eth as EthApiTypes>::Error>

The debug_executionWitness method allows for re-execution of a block with the purpose of generating an execution witness. The witness comprises of a map of all hashed trie nodes to their preimages that were required during the execution of the block, including during state root recomputation.

pub async fn debug_execution_witness_for_block( &self, block: Arc<RecoveredBlock<<<Eth as RpcNodeCore>::Provider as BlockReader>::Block>>, mode: ExecutionWitnessMode, ) -> Result<ExecutionWitness, <Eth as EthApiTypes>::Error>

Generates an execution witness, using the given recovered block.

pub async fn debug_account_at( &self, block_id: BlockId, tx_index: Index, address: Address, ) -> Result<Option<TrieAccount>, <Eth as EthApiTypes>::Error>

Returns account information, including the storage root, after replaying the block through the transaction at the given index.

pub async fn debug_account_info_at( &self, block_id: BlockId, tx_index: Index, address: Address, ) -> Result<Option<AccountInfo>, <Eth as EthApiTypes>::Error>

Returns account information after replaying the block through the transaction at the given index.

pub async fn debug_code_by_hash( &self, hash: FixedBytes<32>, block_id: Option<BlockId>, ) -> Result<Option<Bytes>, <Eth as EthApiTypes>::Error>

Returns the code associated with a given hash at the specified block ID. If no code is found, it returns None. If no block ID is provided, it defaults to the latest block.

pub async fn intermediate_roots( &self, block_hash: FixedBytes<32>, ) -> Result<Vec<FixedBytes<32>>, <Eth as EthApiTypes>::Error>

Executes a block and returns the state root after each transaction.

The block is either canonical or a bad block the engine rejected. Execution stops at the first transaction that is invalid on top of its predecessors, so the result for a bad block holds the roots before that transaction.

Sets the garbage collection target percentage. A negative value disables garbage collection.

async fn debug_set_head( &self, _number: Uint<64, 1>, ) -> Result<(), ErrorObject<'static>>

async fn debug_set_trie_flush_interval( &self, _interval: String, ) -> Result<(), ErrorObject<'static>>

Configures how often in-memory state tries are persisted to disk. The interval needs to be in a format parsable by a time.Duration. Note that the interval is not wall-clock time. Rather it is accumulated block processing time after which the state should be flushed.

async fn debug_standard_trace_bad_block_to_file( &self, _block: BlockNumberOrTag, _opts: Option<GethDebugTracingCallOptions>, ) -> Result<(), ErrorObject<'static>>

where TxReq: Send + Sync + 'static + DeserializeOwned,

Collects all the methods and subscriptions defined in the trait and adds them into a single RpcModule.
