Struct add_ed::ui::DummyUI

pub struct DummyUI<'a> {
    pub input: VecDeque<String>,
    pub print_ui: Option<&'a mut dyn UI>,
}

This is a dummy UI. That means it simulates an UI without interfacing with any users.

How to use:

• Put the input to simulate line-by-line in the input variable.
• If you want output from print commands put the UI to print with in print_ui.

Fields

input: VecDeque<String>

print_ui: Option<&'a mut dyn UI>

fn get_command(
    &mut self,
    _ed: EdState<'_>,
    _prefix: Option<char>
) -> Result<String, &'static str>

Get a command for parsing and execution

fn get_input(
    &mut self,
    _ed: EdState<'_>,
    terminator: char
) -> Result<Vec<String>, &'static str>

Get input lines until given character is entered alone on a line

fn print(&mut self, ed: EdState<'_>, text: &str) -> Result<(), &'static str>

A basic print for output of commands

fn print_selection(
    &mut self,
    ed: EdState<'_>,
    selection: (usize, usize),
    numbered: bool,
    literal: bool
) -> Result<(), &'static str>
