Struct SelectOptionList 

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

An ordered list of selectable values for a SelectPrompt.

Arrays and vectors of values that convert into SelectOption can be converted into a SelectOptionList, which keeps simple string lists concise:

use std::borrow::Cow;

use tui_prompts::{SelectOptionList, SelectPrompt};

let options: SelectOptionList = ["Rust", "Zig", "Go"].into();
let prompt = SelectPrompt::new(Cow::Borrowed("Language"), options);

Implementations

impl<'a> SelectOptionList<'a>

pub const fn new(options: Vec<SelectOption<'a>>) -> SelectOptionList<'a>

Creates an option list from explicit option values.

pub const fn len(&self) -> usize

Returns the number of options in the list.

pub const fn is_empty(&self) -> bool

Returns whether the list contains no options.

pub fn iter(&self) -> impl Iterator<Item = &SelectOption<'a>>

Returns an iterator over the options.

Trait Implementations

impl<'a> Clone for SelectOptionList<'a>

fn clone(&self) -> SelectOptionList<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for SelectOptionList<'a>

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

Formats the value using the given formatter.

impl<'a> Default for SelectOptionList<'a>

fn default() -> SelectOptionList<'a>

Returns the “default value” for a type.

impl<'a> Eq for SelectOptionList<'a>

impl<'a, T> From<Vec<T>> for SelectOptionList<'a>

where T: Into<SelectOption<'a>>,

fn from(options: Vec<T>) -> SelectOptionList<'a>

Converts to this type from the input type.

impl<'a, T, const N: usize> From<[T; N]> for SelectOptionList<'a>

where T: Into<SelectOption<'a>>,

fn from(options: [T; N]) -> SelectOptionList<'a>

Converts to this type from the input type.

impl<'a> Hash for SelectOptionList<'a>

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> IntoIterator for &'a SelectOptionList<'a>

type IntoIter = Iter<'a, SelectOption<'a>>

Which kind of iterator are we turning this into?

type Item = &'a SelectOption<'a>

The type of the elements being iterated over.

fn into_iter(self) -> <&'a SelectOptionList<'a> as IntoIterator>::IntoIter

Creates an iterator from a value.

impl<'a> PartialEq for SelectOptionList<'a>

fn eq(&self, other: &SelectOptionList<'a>) -> 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.
