Provided methods

fn complete(
    &self,
    line: &str,
    pos: usize,
    ctx: &Context<'_>
) -> Result<(usize, Vec<Self::Candidate>)>

Takes the currently edited line with the cursor position and returns the start position and the completion candidates for the partial word to be completed.

("ls /usr/loc", 11) => Ok((3, vec!["/usr/local/"]))

fn update(&self, line: &mut LineBuffer, start: usize, elected: &str)

Updates the edited line with the elected candidate.
