Enum rustc_hir::hir::BorrowKind
source · [−]pub enum BorrowKind {
Ref,
Raw,
}Expand description
The kind of borrow in an AddrOf expression,
e.g., &place or &raw const place.
Variants
Ref
A normal borrow, &$expr or &mut $expr.
The resulting type is either &'a T or &'a mut T
where T = typeof($expr) and 'a is some lifetime.
Raw
A raw borrow, &raw const $expr or &raw mut $expr.
The resulting type is either *const T or *mut T
where T = typeof($expr).
