Implementations

impl<P, B: Backend> Input<P, B>

pub fn new(prompt: P, backend: &mut B) -> Input<P, &mut B>

Creates a new Input. This won’t do anything until it is run.

pub fn hide_cursor(self) -> Self

Hides the cursor while running the input. This won’t do anything until it is run.

pub fn on_esc(self, on_esc: OnEsc) -> Self

What to do after receiving a Esc.

For OnEsc::Terminate - an Error::Aborted will be returned. For OnEsc::SkipQuestion - the currently shown prompt will be cleared, and Ok(None) will be returned. For OnEsc::Ignore - no special behaviour will be applied to the Esc key. Like other keys, the Esc key will be passed to the prompt to handle.

impl<P: Prompt, B: Backend> Input<P, B>

pub fn run<E>(self, events: &mut E) -> Result<Option<P::Output>>

where E: EventIterator,

Display the prompt and process events until the user presses Enter.

After the user presses Enter, validate will be called.
