Same, but make x value of the loop expression (only in actual loop).Įxit not only this loop, but the enclosing one marked with 'label. Loop label, EX REF useful for flow control in nested loops. On proper Iterator STD then x = next() until exhausted (first None).Ĭonditional branch REF if expression is true. BK STD REFĮffectively converts any IntoIterator STD type into proper iterator first. Loop, REF run while expression x is true. Guarantees S is well-behaved w.r.t T people may use T on S safely.Ĭontrol execution within a function. Guarantees to compiler " I have checked requirements, trust me". of T can cause UB implementor must check". Means " calling can cause UB, ↓ YOU must check requirements". If you enjoy debugging segfaults Friday night unsafe code. Move closure REF taking ownership i.e., y transferred into closure.Ĭlosures sometimes look like logical ORs (here: return a closure).

Opinion 💬 - If you have never seen or used any Rust it might be good to visit one of the links above before continuing the next chapter might feel a bit terse otherwise. In addition, have a look at the usual suspects.
