PtrMutWide

Struct PtrMutWide 

Source
pub struct PtrMutWide<'mem> { /* private fields */ }
Expand description

A type-erased, mutable wide pointer to an initialized value.

Like PtrMut, but for unsized types where metadata is needed. Provides mutable access to the underlying object, whose borrow is tracked by lifetime 'mem.

Implementations§

Source§

impl<'mem> PtrMutWide<'mem>

Source

pub const fn new<T: ?Sized>(ptr: *mut T) -> Self

Creates a new mutable wide pointer from a raw pointer to a (potentially unsized) object.

§Arguments
  • ptr - Raw mutable pointer to the object. Can be a pointer to a DST (e.g., slice, trait object).
§Panics

Panics if a thin pointer is provided where a wide pointer is expected.
