# Struct CatchUnwindData

Source

    pub struct CatchUnwindData<'tcx> {
        catch_fn: Pointer,
        data: ImmTy<'tcx>,
        dest: MPlaceTy<'tcx>,
        ret: Option<BasicBlock>,
    }

Expand description

Holds all of the relevant data for when unwinding hits a `try` frame.

## Fields§

§`catch_fn: Pointer`

The `catch_fn` callback to call in case of a panic.

§`data: ImmTy<'tcx>`

The `data` argument for that callback.

§`dest: MPlaceTy<'tcx>`

The return place from the original call to `try`.

§`ret: Option<BasicBlock>`

The return block from the original call to `try`.
