Trait situ::DropRaw

pub trait DropRaw {
    unsafe fn drop_raw(this: Mut<'_, Self>);
}

A type that can be dropped through a raw pointer, without creating an intermediary reference.

This is different from ptr::drop_in_place because it does not invoke Drop::drop with a mutable reference. DropRaw::drop_raw is the last method called with access to the value; effectively a raw version of Drop. This is to avoid creating an intermediate reference, which narrows provenance for the dropped value.

Types that implement Copy may have their raw drops elided.

Required Methods

unsafe fn drop_raw(this: Mut<'_, Self>)

Drops the value pointed to by this.

Safety

• The value pointed to by this must be valid for dropping.
• After calling drop_raw, the value pointed to by this must never be accessed again.
