Struct ethcore::trace::TraceDB

pub struct TraceDB<T> where
    T: DatabaseExtras,  { /* fields omitted */ }

Database to store transaction execution trace.

Whenever a transaction is executed by EVM it's execution trace is stored in trace database. Each trace has information, which contracts have been touched, which have been created during the execution of transaction, and which calls failed.

Methods

impl<T> TraceDB<T> where     T: DatabaseExtras,

pub fn new(config: Config, db: Arc<BlockChainDB>, extras: Arc<T>) -> Self

Creates new instance of TraceDB.

pub fn collect_garbage(&self)

Ticks our cache system and throws out any old data.
