Performs completion for Prompter when triggered by a user input sequence

Required Methods

fn complete(
    &self,
    word: &str,
    prompter: &Prompter<Term>,
    start: usize,
    end: usize
) -> Option<Vec<Completion>>

Returns the set of possible completions for the prefix word.

Provided Methods

fn word_start(&self, line: &str, end: usize, prompter: &Prompter<Term>) -> usize

Returns the starting position of the word under the cursor.

The default implementation uses Prompter::word_break_chars() to detect the start of a word.

fn quote<'a>(&self, word: &'a str) -> Cow<'a, str>

Quotes a possible completion for insertion into input.

The default implementation returns the word, as is.

fn unquote<'a>(&self, word: &'a str) -> Cow<'a, str>

Unquotes a piece of user input before searching for completions.

The default implementation returns the word, as is.
