Struct OneOfQuestion 

pub struct OneOfQuestion {
    pub variants: Vec<Variant>,
    pub default: Option<usize>,
}

Configuration for a OneOf question (choose exactly one variant).

Used for enums where the user selects one variant, then answers any follow-up questions for that variant.

Fields

variants: Vec<Variant>

The available variants to choose from.

default: Option<usize>

Default selected variant index (if any).

Implementations

impl OneOfQuestion

pub fn new(variants: Vec<Variant>) -> Self

Create a new OneOf question with the given variants.

pub fn with_default(variants: Vec<Variant>, default: usize) -> Self

Create with a default selection.

pub fn variants(&self) -> &[Variant]

Get the variants.

pub fn variants_mut(&mut self) -> &mut Vec<Variant>

Get a mutable reference to the variants.

Trait Implementations

impl Clone for OneOfQuestion

fn clone(&self) -> OneOfQuestion

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OneOfQuestion

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for OneOfQuestion

fn eq(&self, other: &OneOfQuestion) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
