infix operator || { associativity left precedence 110 } Declarations func || <T : BooleanType, U : BooleanType>(_: T, rhs: () throws -> U) If lhs is true, return it. Otherwise, evaluate rhs and return its boolValue. Declaration func ||<T : BooleanType, U : BooleanType>(lhs: T, @autoclosure rhs: () throws -> U) -> Bool func || <T : BooleanType>(_: T, rhs: () throws -> Bool) Declaration func ||<T : BooleanType>(lhs: T, @autoclosure rhs: () throws -> Bool) -> Bool
