Struct PtrConstWide 

pub struct PtrConstWide<'mem> { /* private fields */ }

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

Like PtrConst, but for unsized types where metadata is needed. Cannot be null (but may be dangling for ZSTs). The lifetime 'mem represents the borrow of the underlying memory, which must remain valid and initialized.

Implementations

impl<'mem> PtrConstWide<'mem>

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

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

Arguments

• ptr - Raw 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.

pub fn as_byte_ptr(self) -> *const u8

Returns the underlying data pointer as a pointer to u8 (the address of the object).

pub unsafe fn get<T: ?Sized>(self) -> &'mem T

Borrows the underlying object as a reference of type T.

Safety

• T must be the actual underlying (potentially unsized) type of the pointed-to memory.
• The memory must remain valid and not be mutated while this reference exists.
• The pointer must be correctly aligned and point to a valid, initialized value for type T.
