trait Range 

pub trait Range<T> {
    // Provided methods
    fn start(&self) -> Option<&T> { ... }
    fn end(&self) -> Option<&T> { ... }
}

提供方法

fn start(&self) -> Option<&T>

fn end(&self) -> Option<&T>

对外部类型的实现

impl<T> Range<T> for Range<T>

fn start(&self) -> Option<&T>

fn end(&self) -> Option<&T>

impl<T> Range<T> for RangeFrom<T>

fn start(&self) -> Option<&T>

impl<T> Range<T> for RangeFull

impl<T> Range<T> for RangeTo<T>

fn end(&self) -> Option<&T>
