core::intrinsics::needs_drop
[−]
[src]
pub unsafe extern "rust-intrinsic" fn needs_drop<T>() -> bool
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
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.
