Enum PerfLine 

#[non_exhaustive]
pub enum PerfLine {
    Frame(FrameRecord),
    Snapshot(HeapSnapshot),
    Diff(HeapDiff),
}

One line of a perf trace, as agents read it (ADR-0046 §7): a JSON object tagged by kind, one a line (serde_json::to_string(&line) and a newline).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Frame(FrameRecord)

What one frame measured: {"kind":"frame","frame":12,…}.

Snapshot(HeapSnapshot)

What held the heap at a frame: {"kind":"snapshot","frame":600,"live_bytes":…,"tags":[…],…}.

Diff(HeapDiff)

What changed between two snapshots: {"kind":"diff","from":1,"to":600,"live_bytes":98304,"tags":[…]}.
