Implementations

impl TraceStep

pub fn snapshot_ref(&self) -> StepSnapshotRef<'_>

Borrows the machine state this step captured, without copying it.

A step records the same data twice: the flat stack/memory/storage fields, and a StepSnapshot that additionally carries the storage diff. Whichever is populated, this returns a view of it.

Prefer this over TraceStep::normalized_snapshot anywhere that walks a trace. Traces routinely run to hundreds of thousands of steps and each one’s memory can be tens of kilobytes, so copying per step — or, as variable decoding does, per variable per step — dominates the cost of reading a trace.

pub fn normalized_snapshot(&self) -> StepSnapshot

Copies the machine state this step captured into an owned StepSnapshot.

Use this only when ownership is genuinely required; TraceStep::snapshot_ref is the same view without the copy.
