A prompt that asks the user to choose from a list of items.

Implementations

impl Select

pub fn new() -> Result<Self, InteractionError>

Create the prompt, returning an error if interactive context is incorrectly set.

pub fn set_prompt(&mut self, prompt: String)

Set the prompt.

pub fn with_prompt<S: ToString>(&mut self, prompt: S) -> &mut Self

Builder pattern for Self::set_prompt

pub fn interact(&mut self) -> Result<usize, InteractionError>

Present the prompt to the user. May return an error if in a non-interactive context, or interaction fails for any other reason

impl Select

pub fn set_default(&mut self, value: usize)

Set the default selection. If the user does not input anything, this value will be used instead.

pub fn with_default<I: Into<usize>>(&mut self, value: I) -> &mut Self

Builder pattern for Self::set_default

impl Select

pub fn add_items<S: ToString>(&mut self, items: &[S])

Add items to be displayed in the selection prompt.

pub fn with_items<S: ToString>(&mut self, items: &[S]) -> &mut Self

Builder pattern for Self::add_items.

NOTE: if this function is called multiple times, it will add ALL items to the builder.
