[−][src]Function std::intrinsics::needs_drop
pub extern "rust-intrinsic" fn needs_drop<T>() -> bool
🔬 This is a nightly-only experimental API. (core_intrinsics #0)
intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library
Returns true if the actual type given as T requires drop
glue; returns false if the actual type provided for T
implements Copy.
If the actual type neither requires drop glue nor implements
Copy, then may return true or false.
The stabilized version of this intrinsic is
std::mem::needs_drop.
