Struct FrameExtra 

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>,
}

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.
