Struct ChoiceOptions

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

Writer for a choice options array.

This struct is created by Field::choice_options.

Implementations

impl<'a> ChoiceOptions<'a>

pub fn option(&mut self, value: TextStr<'_>) -> &mut Self

Add an option with the given value.

pub fn options<'b>( &mut self, values: impl IntoIterator<Item = TextStr<'b>>, ) -> &mut Self

Add options with the given values.

pub fn export( &mut self, value: TextStr<'_>, export_value: TextStr<'_>, ) -> &mut Self

Add an option with the given value and export value.

pub fn exports<'b>( &mut self, values: impl IntoIterator<Item = (TextStr<'b>, TextStr<'b>)>, ) -> &mut Self

Add options with the given pairs of value and export value.

Methods from Deref<Target = Array<'a>>

pub fn len(&self) -> i32

The number of written items.

pub fn is_empty(&self) -> bool

Whether no items have been written so far.

pub fn push(&mut self) -> Obj<'_>

Start writing an arbitrary item.

pub fn item<T: Primitive>(&mut self, value: T) -> &mut Self

Write an item with a primitive value.

This is a shorthand for array.push().primitive(value).

pub fn items<T: Primitive>( &mut self, values: impl IntoIterator<Item = T>, ) -> &mut Self

Write a sequence of items with primitive values.
