Trait IterateBounds

pub trait IterateBounds {
    // Required method
    fn into_bounds(self) -> (Option<Vec<u8>>, Option<Vec<u8>>);
}

A range which can be set as iterate bounds on crate::ReadOptions.

See crate::ReadOptions::set_iterate_range for documentation and examples.

Required Methods

fn into_bounds(self) -> (Option<Vec<u8>>, Option<Vec<u8>>)

Converts object into lower and upper bounds pair.

If this object represents range with one of the bounds unset, corresponding element is returned as None. For example, ..upper range would be converted into (None, Some(upper)) pair.
