To be called for tab-completion.

Required Associated Types

type Candidate: Candidate

Specific completion candidate.

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, cl: &mut Changeset )

Updates the edited line with the elected candidate.
