pub const fn contract_check_ensures<C: Fn(&Ret) -> bool + Copy, Ret>(
cond: C,
ret: Ret,
) -> Ret🔬This is a nightly-only experimental API. (
contracts_internals #128044)Expand description
Check if the post-condition cond has been met.
By default, if contract_checks is enabled, this will panic with no unwind if the condition
returns false.
Note that this function is a no-op during constant evaluation.
