Implementations§

source§

impl<Ext: BackendExternalities, Mem> State<Ext, Mem>

source

pub fn into_parts(self) -> (Ext, UndefinedTerminationReason)

Transforms Self into tuple of externalities, memory and termination reason returned after the execution.

source

pub fn terminate<T: Debug, WasmCallErr: Debug>( self, res: Result<T, WasmCallErr>, gas: u64, ) -> (Ext, TerminationReason)

Terminates backend work after execution.

The function handles res, which is the result of gear wasm program entry point invocation, and the termination reason.

If the res is Ok, then execution considered successful and the termination reason will have the corresponding value.

If the res is Err, then execution is considered to end with an error and the actual termination reason, which stores more precise information about the error, is returned.

There’s a case, when res is Err, but termination reason has a value for the successful ending of the execution. This is the case of calling unreachable panic in the program.
