source

pub fn memory(&self) -> &MemoryInstance

source

pub const fn result(&self) -> &ScriptExecutionResult

ScriptExecutionResult of the error that caused this backtrace.

source

pub const fn initial_balances(&self) -> &InitialBalances

The initial balances.

source

pub fn into_inner( self, ) -> (Vec<CallFrame>, ContractId, [Word; 64], MemoryInstance, ScriptExecutionResult, InitialBalances)
