Enum rustc::ty::UpvarCapture

pub enum UpvarCapture<'tcx> {
    ByValue,
    ByRef(UpvarBorrow<'tcx>),
}

🔬 This is a nightly-only experimental API. (rustc_private)

Information describing the capture of an upvar. This is computed during typeck, specifically by regionck.

Variants

ByValue

🔬 This is a nightly-only experimental API. (rustc_private)

Upvar is captured by value. This is always true when the closure is labeled move, but can also be true in other cases depending on inference.

ByRef(UpvarBorrow<'tcx>)

🔬 This is a nightly-only experimental API. (rustc_private)

Upvar is captured by reference.
