Trait tcalc_rustyline::completion::Completer

pub trait Completer {
    fn complete(&self, line: &str, pos: usize) -> Result<(usize, Vec<String>)>;

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

To be called for tab-completion.

Required methods

fn complete(&self, line: &str, pos: usize) -> Result<(usize, Vec<String>)>

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