Struct rustc_mir::transform::check_consts::ops::MutBorrow

pub struct MutBorrow(pub BorrowKind);

This op is for &mut borrows in the trailing expression of a constant which uses the “enclosing scopes rule” to leak its locals into anonymous static or const items.

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
