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).
