Expand description

Extra data stored with each stack frame

Fields§

§borrow_tracker: Option<FrameState>

Extra data for Stacked Borrows.

§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.

§is_user_relevant: bool

Indicates whether a Frame is part of a workspace-local crate and is also not #[track_caller]. We compute this once on creation and store the result, as an optimization. This is used by MiriMachine::current_span and MiriMachine::caller_span
