pub fn rustc_peek<T>(_: T) -> T🔬This is a nightly-only experimental API. (
core_intrinsics)This item is validated for IEC 61508 (SIL 2) and ISO 26262 (ASIL B).
Expand description
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.
This intrinsic should not be used outside of the compiler.
