## FrameExtra

# Struct FrameExtra

Source

    pub struct FrameExtra<'tcx> {
        pub borrow_tracker: Option<FrameState>,
        pub catch_unwind: Option<CatchUnwindData<'tcx>>,
        pub timing: Option<DetachedTiming>,
        pub user_relevance: u8,
        pub data_race: Option<FrameState>,
    }

Expand description

Extra data stored with each stack frame

## Fields§

§`borrow_tracker: Option<FrameState>`

Extra data for the Borrow Tracker.

§`catch_unwind: Option<CatchUnwindData<'tcx>>`

If this is Some(), then this is a special “catch unwind” frame (the frame of `try_fn` called by `try`). When this frame is popped during unwinding a panic, we stop unwinding, use the `CatchUnwindData` to handle catching.

§`timing: Option<DetachedTiming>`

If `measureme` profiling is enabled, holds timing information for the start of this frame. When we finish executing this frame, we use this to register a completed event with `measureme`.

§`user_relevance: u8`

Indicates how user-relevant this frame is. `#[track_caller]` frames are never relevant. Frames from user-relevant crates are maximally relevant; frames from other crates are less relevant.

§`data_race: Option<FrameState>`

Data race detector per-frame data.

## Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain `repr(...)` attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
