Macro mirai_annotations::checked_precondition

macro_rules! checked_precondition {
    ($condition : expr) => { ... };
    ($condition : expr, $message : literal) => { ... };
    ($condition : expr, $($arg : tt) *) => { ... };
}

Equivalent to the standard assert! when used with an unmodified Rust compiler. When compiled with MIRAI, this causes MIRAI to assume the condition at the point where it appears in a function, but to also add it a precondition that must be verified by the caller of the function.
