Trait IndexRange 

pub trait IndexRange {
    // Required methods
    fn start(&self) -> Option<usize>;
    fn end(&self) -> Option<usize>;

    // Provided method
    fn to_range(&self, len: usize) -> Result<Range<usize>> { ... }
}

IndexRange is implemented by Rust’s built-in range types, produced by range syntax like .., a.., ..b or c..d.

Required Methods

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

Start index (inclusive)

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

End index (exclusive)

Provided Methods

fn to_range(&self, len: usize) -> Result<Range<usize>>

len: the size of whatever container that is being indexed
