Enum rustc_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)
.

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
