Variants§
ReifyFnPointer
Go from a fn-item type to a fn-pointer type.
UnsafeFnPointer
Go from a safe fn pointer to an unsafe fn pointer.
ClosureFnPointer(Safety)
Go from a non-capturing closure to an fn pointer or an unsafe fn pointer. It cannot convert a closure that requires unsafe.
MutToConstPointer
Go from a mut raw pointer to a const raw pointer.
ArrayToPointer
Go from *const [T; N]
to *const T
Unsize
Unsize a pointer/reference value, e.g., &[T; n]
to
&[T]
. Note that the source could be a thin or fat pointer.
This will do things like convert thin pointers to fat
pointers, or convert structs containing thin pointers to
structs containing fat pointers, or convert between fat
pointers.

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.
