sourcefn range<'a>(
&'a self,
start: Option<&[u8]>,
end: Option<&[u8]>,
order: Order
) -> Box<dyn Iterator<Item = Record> + 'a>
fn range<'a>(
&'a self,
start: Option<&[u8]>,
end: Option<&[u8]>,
order: Order
) -> Box<dyn Iterator<Item = Record> + 'a>
range allows iteration over a set of keys, either forwards or backwards uses standard rust range notation, and eg db.range(b“foo“..b“bar“) also works reverse
sourcefn get(&self, key: &[u8]) -> Option<Vec<u8>>
fn get(&self, key: &[u8]) -> Option<Vec<u8>>
Returns None when key does not exist.
Returns Some(Vec
fn set(&mut self, key: &[u8], value: &[u8])
