[−][src]Function std::intrinsics::rustc_peek
pub unsafe extern "rust-intrinsic" fn rustc_peek<T>(T) -> T
🔬 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
Magic intrinsic that derives its meaning from attributes attached to the function.
For example, dataflow uses this to inject static assertions so
that rustc_peek(potentially_uninitialized)
would actually
double-check that dataflow did indeed compute that it is
uninitialized at that point in the control flow.
