Struct TinyBoxSized

#[repr(C)]
pub struct TinyBoxSized<T: ?Sized, const S: usize>(/* private fields */);

Implementations

impl<T: ?Sized, const S: usize> TinyBoxSized<T, S>

pub unsafe fn read_raw(src: *mut T) -> Self

Safety

Behavior is undefined if any of the following conditions are violated:

• src must be valid for reads.
• src must be properly aligned.
• src must point to a properly initialized value of type T.
• the value at src must not be used or dropped after read_raw is called.

Like ptr::read, read_raw creates a bitwise copy of T, regardless of whether T is Copy. If T is not Copy, using the value at *src after calling read_raw can violate memory safety. This also applies for dropping dte value at src. It is recommended, that mem::forget is called on the value at src.

Note that even if T has size 0, the pointer must be non-null and properly aligned.
