Function std::intrinsics::init_dropped

pub unsafe extern "rust-intrinsic" fn init_dropped<T>() -> T

Unstable (core_intrinsics)

: intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

Creates a value initialized to so that its drop flag, if any, says that it has been dropped.

init_dropped is unsafe because it returns a datum with all of its bytes set to the drop flag, which generally does not correspond to a valid value.

This intrinsic is likely to be deprecated in the future when Rust moves to non-zeroing dynamic drop (and thus removes the embedded drop flags that are being established by this intrinsic).
