Trait CompletionInput

pub trait CompletionInput: Sized {
    // Required methods
    fn args(&self) -> Vec<&str>;
    fn arg_index(&self) -> usize;
    fn char_index(&self) -> usize;

    // Provided methods

}

Required Methods

fn args(&self) -> Vec<&str>

fn arg_index(&self) -> usize

fn char_index(&self) -> usize

Provided Methods

fn current_word(&self) -> &str

fn previous_word(&self) -> &str

fn complete_subcommand<'a, T>(&self, subcommands: T) -> Vec<String>

where T: IntoIterator<Item = &'a str>,

Given a list of subcommands, print any that match the current word

fn complete_directory(&self) -> Vec<String>

Print directory completions based on the current word

fn complete_file(&self) -> Vec<String>

Print file completions based on the current word Also returns directories because the user may be entering a file within that directory

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
