Dylan DPC b22559f547 Rollup merge of #103346 - HeroicKatora:metadata_of_const_pointer_argument, r=dtolnay ... Adjust argument type for mutable with_metadata_of (#75091) The method takes two pointer arguments: one `self` supplying the pointer value, and a second pointer supplying the metadata. The new parameter type more clearly reflects the actual requirements. The provenance of the metadata parameter is disregarded completely. Using a mutable pointer in the call site can be coerced to a const pointer while the reverse is not true. In some cases, the current parameter type can thus lead to a very slightly confusing additional cast. [Example](cad93775eb). ```rust // Manually taking an unsized object from a `ManuallyDrop` into another allocation. let val: &core::mem::ManuallyDrop<T> = …; let ptr = val as *const _ as *mut T; let ptr = uninit.as_ptr().with_metadata_of(ptr); ``` This could then instead be simplified to: ```rust // Manually taking an unsized object from a `ManuallyDrop` into another allocation. let val: &core::mem::ManuallyDrop<T> = …; let ptr = uninit.as_ptr().with_metadata_of(&**val); ``` Tracking issue: https://github.com/rust-lang/rust/issues/75091 ``@dtolnay`` you're reviewed #95249, would you mind chiming in?		2022-10-22 16:28:09 +05:30
