Struct slint::ModelRc

pub struct ModelRc<T>(_);

A Reference counted Model.

The ModelRc struct holds something that implements the Model trait. This is used in for expressions in the .slint language. Array properties in the .slint language are holding a ModelRc.

An empty model can be constructed with ModelRc::default(). Use ModelRc::new() To construct a ModelRc from something that implements the Model trait. It is also possible to use the From trait to convert from Rc<dyn Model>.

Implementations

impl<T> ModelRc<T>

pub fn new(model: impl Model<Data = T> + 'static) -> ModelRc<T>

Trait Implementations

impl<T> Clone for ModelRc<T>

pub fn clone(&self) -> ModelRc<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for ModelRc<T>

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

Formats the value using the given formatter.

impl<T> Default for ModelRc<T>

pub fn default() -> ModelRc<T>

Construct an empty model

impl<T, M> From<Rc<M>> for ModelRc<T> where
    M: 'static + Model<Data = T>, 

pub fn from(model: Rc<M>) -> ModelRc<T>

Performs the conversion.

impl<T> From<Rc<dyn Model<Data = T> + 'static>> for ModelRc<T>

pub fn from(model: Rc<dyn Model<Data = T> + 'static>) -> ModelRc<T>

Performs the conversion.

impl<T> Model for ModelRc<T>

type Data = T

The model data: A model is a set of row and each row has this data

pub fn row_count(&self) -> usize

The amount of row in the model

pub fn row_data(&self, row: usize) -> Option<<ModelRc<T> as Model>::Data>

Returns the data for a particular row. This function should be called with row < row_count().

pub fn set_row_data(&self, row: usize, data: <ModelRc<T> as Model>::Data)

Sets the data for a particular row.

pub fn model_tracker(&self) -> &dyn ModelTracker

The implementation should return a reference to its ModelNotify field.

pub fn as_any(&self) -> &(dyn Any + 'static)

Return something that can be downcast’ed (typically self)

fn iter(&self) -> ModelIterator<'_, Self::Data>

Returns an iterator visiting all elements of the model.

impl<T> PartialEq<ModelRc<T>> for ModelRc<T>

pub fn eq(&self, other: &ModelRc<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl<T> TryInto<Rc<dyn Model<Data = T> + 'static>> for ModelRc<T>

type Error = ()

The type returned in the event of a conversion error.

pub fn try_into(
    self
) -> Result<Rc<dyn Model<Data = T> + 'static>, <ModelRc<T> as TryInto<Rc<dyn Model<Data = T> + 'static>>>::Error>

Performs the conversion.
