Trait Range

pub trait Range {
    // Required method
    fn len(&self) -> usize;

    // Provided method
    fn is_empty(&self) -> bool { ... }
}

Required Methods

Returns the remaining length of self. The returned length need not be the same as the number of items left in the stream.

Provided Methods

fn is_empty(&self) -> bool

Returns true if the range does not contain any elements (Range::len() == 0)
