Struct PromptModule 

pub struct PromptModule<Q> { /* private fields */ }

A collection of questions and answers for previously answered questions.

Unlike prompt, this allows you to control how many questions you want to ask, and ask with previous answers as well.

Implementations

impl<'a, Q> PromptModule<Q>

where Q: Iterator<Item = Question<'a>>,

pub fn new<I>(questions: I) -> Self

where I: IntoIterator<IntoIter = Q, Item = Question<'a>>,

Creates a new PromptModule with the given questions

pub fn with_answers(self, answers: Answers) -> Self

Creates a PromptModule with the given questions and answers

pub fn prompt(&mut self) -> Result<Option<&mut Answer>>

Available on crate features crossterm or termion only.

Prompt a single question with the default Backend and EventIterator.

This may or may not actually prompt the question based on what when and ask_if_answered returns for that particular question.

pub fn prompt_with<B, E>( &mut self, backend: &mut B, events: &mut E, ) -> Result<Option<&mut Answer>>

where B: Backend, E: EventIterator,

Prompt a single question with the given Backend and EventIterator.

This may or may not actually prompt the question based on what when and ask_if_answered returns for that particular question.

pub fn prompt_all(self) -> Result<Answers>

Available on crate features crossterm or termion only.

Prompt all remaining questions with the default Backend and EventIterator.

It consumes self and returns the answers to all the questions asked.

pub fn prompt_all_with<B, E>( self, backend: &mut B, events: &mut E, ) -> Result<Answers>

where B: Backend, E: EventIterator,

Prompt all remaining questions with the given Backend and EventIterator.

It consumes self and returns the answers to all the questions asked.

pub fn into_answers(self) -> Answers

Consumes self returning the answers to the previously asked questions.

Trait Implementations

impl<Q: Clone> Clone for PromptModule<Q>

fn clone(&self) -> PromptModule<Q>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Q: Debug> Debug for PromptModule<Q>

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

Formats the value using the given formatter.

impl<Q: PartialEq> PartialEq for PromptModule<Q>

fn eq(&self, other: &PromptModule<Q>) -> 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.
