Function core::ptr::from_raw_parts

pub const fn from_raw_parts<T: ?Sized>(
    data_pointer: *const impl Thin,
    metadata: <T as Pointee>::Metadata,
) -> *const T

🔬This is a nightly-only experimental API. (ptr_metadata #81513)

Forms a (possibly-wide) raw pointer from a data pointer and metadata.

This function is safe but the returned pointer is not necessarily safe to dereference. For slices, see the documentation of slice::from_raw_parts for safety requirements. For trait objects, the metadata must come from a pointer to the same underlying erased type.
