Enum UpvarCapture 

pub enum UpvarCapture {
    ByRef(BorrowKind),
    ByUse,
    ByValue,
}

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

Variants

ByRef(BorrowKind)

Upvar is captured by reference.

ByUse

Upvar is captured by use. This is true when the closure is labeled use.

ByValue

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.
