Leko => YSITD: 例如 trait A { fn a(&self) -> i32; } trait B { fn b(&self) -> i32; } trait AB{ fn a(&self) -> i32; fn b(&self) -> i32; } struct foo; impl AB for foo; fn bar<T: A+B>(_: T); bar(foo) 會動ㄇ #5dc5840372293a2d6cf1a7ae

Leko says to YSITD

例如 trait A { fn a(&self) -> i32; } trait B { fn b(&self) -> i32; } trait AB{ fn a(&self) -> i32; fn b(&self) -> i32; } struct foo; impl AB for foo; fn bar<T: A+B>(_: T); bar(foo) 會動ㄇ
