Db provides an interface to query tracesdb.

Required Methods

fn tracing_enabled(&self) -> bool

Returns true if tracing is enabled. Otherwise false.

fn import(&self, batch: &mut DBTransaction, request: ImportRequest)

Imports new block traces.

fn trace(
    &self,
    block_number: BlockNumber,
    tx_position: usize,
    trace_position: Vec<usize>
) -> Option<LocalizedTrace>

Returns localized trace at given position.

fn transaction_traces(
    &self,
    block_number: BlockNumber,
    tx_position: usize
) -> Option<Vec<LocalizedTrace>>

Returns localized traces created by a single transaction.

fn block_traces(&self, block_number: BlockNumber) -> Option<Vec<LocalizedTrace>>

Returns localized traces created in given block.

Important traits for Vec<u8>

impl Write for Vec<u8>

fn filter(&self, filter: &Filter) -> Vec<LocalizedTrace>

Filter traces matching given filter.
