Struct Outcome 

#[non_exhaustive]
pub struct Outcome {
    pub returns: VMLogicResult<Option<Vec<u8>>, FunctionCallError>,
    pub logs: Vec<String>,
    pub events: Vec<Event>,
    pub root_hash: Option<[u8; 32]>,
    pub artifact: Vec<u8>,
    pub proposals: BTreeMap<[u8; 32], Vec<u8>>,
    pub approvals: Vec<[u8; 32]>,
}

Represents the final outcome of a VM execution.

This struct aggregates all the results and side effects of function calls, such as the return value, logs, events, and state changes.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

returns: VMLogicResult<Option<Vec<u8>>, FunctionCallError>

The result of the execution. Ok(Some(value)) for a successful return, Ok(None) for no return, and Err for a trap or execution error.

logs: Vec<String>

All log messages generated during the execution.

events: Vec<Event>

All events emitted during the execution.

root_hash: Option<[u8; 32]>

The new state root hash if there were commits during the execution.

artifact: Vec<u8>

The binary artifact produced if there were commits during the execution.

proposals: BTreeMap<[u8; 32], Vec<u8>>

A map of proposals created during execution, having proposal ID as a key.

approvals: Vec<[u8; 32]>

A list of approvals submitted during execution.
