Trait Completer

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

    // Provided method
    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”, 11) => Ok((3, vec![“/usr/local/”]))

Provided Methods

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

Updates the edited line with the elected candidate.
