Struct Confirm 

pub struct Confirm<'a> { /* private fields */ }

Builder for a yes/no confirmation prompt.

Wraps Terminal::confirm with a chainable configuration API. Call Confirm::ask to display the prompt and block until the user answers.

Example

use vecli::Confirm;

let confirmed = Confirm::new("Delete file?")
    .default(false)
    .ask();

Implementations

impl<'a> Confirm<'a>

pub fn new(prompt: &'a str) -> Self

Defaults to false when the user presses Enter, with the default indicator visible.
