Variants§
Inspect
Being inspected in some way, like loading a len.
Copy
Consumed as part of an operand.
Move
Consumed as part of an operand.
Shared borrow.
ShallowBorrow
Shallow borrow.
UniqueBorrow
Unique borrow.
AddressOf
AddressOf for *const pointer.
Projection
Used as base for another place, e.g., x
in x.y
. Will not mutate the place.
For example, the projection x.y
is not marked as a mutation in these cases:
ⓘ
z = x.y;
f(&x.y);

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.
