Source

pub fn report(self, val: bool) -> Self

Indicates whether or not to report the chosen selection after interaction.

The default is to report the chosen selection.

Source

pub fn wait_for_newline(self, wait: bool) -> Self

Sets when to react to user input.

When false (default), we check on each user keystroke immediately as it is typed. Valid inputs can be one of ‘y’, ‘n’, or a newline to accept the default.

When true, the user must type their choice and hit the Enter key before proceeding. Valid inputs can be “yes”, “no”, “y”, “n”, or an empty string to accept the default.

pub fn default(self, val: bool) -> Self

Sets a default.

Out of the box the prompt does not have a default and will continue to display until the user inputs something and hits enter. If a default is set the user can instead accept the default with enter.

pub fn interact(self) -> Result<bool>

Enables user interaction and returns the result.

The dialog is rendered on stderr.

Result contains bool if user answered “yes” or “no” or default (configured in default if pushes enter. This unlike interact_opt does not allow to quit with ‘Esc’ or ‘q’.

pub fn interact_opt(self) -> Result<Option<bool>>

Enables user interaction and returns the result.

The dialog is rendered on stderr.

Result contains Some(bool) if user answered “yes” or “no” or Some(default) (configured in default) if pushes enter, or None if user cancelled with ‘Esc’ or ‘q’.

§Example

use dialoguer::Confirm;

fn main() {
    let confirmation = Confirm::new()
        .interact_opt()
        .unwrap();

    match confirmation {
        Some(answer) => println!("User answered {}", if answer { "yes" } else { "no " }),
        None => println!("User did not answer")
    }
}
