Enum SimStatus 

Source 
pub enum SimStatus {
    Success,
    Revert,
    Halt {
        reason: String,
    },
}
Expand description

Outcome of a balance-delta-tracking simulation.

Produced by EvmCache::simulate_call_with_balance_deltas and EvmCache::simulate_with_transfer_tracking: a successful call together with the per-token balance changes it caused, its emitted logs, the touched access list, and its raw return data. Execution outcome of a simulated call.

Lets a caller distinguish a successful call — even one that emitted no logs, such as a view call — from a revert or a halt, without guessing from logs or output. Revert payloads live in CallSimulationResult::output and can be decoded with RevertDecoder; only Halt carries extra data here, since its reason has nowhere else to live.

Variants§

§

Success

The call returned successfully.

§

Revert

The call reverted; the revert payload (if any) is in output.

§

Halt

The call halted (e.g. out of gas, invalid opcode).

Fields

§reason: String

Debug-formatted halt reason.
