Struct i_slint_core::model::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) -> Self

Trait Implementations

impl<T> Clone for ModelRc<T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for ModelRc<T>

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

Formats the value using the given formatter.

impl<T> Default for ModelRc<T>

fn default() -> Self

Construct an empty model

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

fn from(model: Rc<M>) -> Self

Converts to this type from the input type.

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

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

Converts to this type from the input type.

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

fn row_count(&self) -> usize

The amount of row in the model

fn row_data(&self, row: usize) -> Option<Self::Data>

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

fn set_row_data(&self, row: usize, data: Self::Data)

Sets the data for a particular row.

fn model_tracker(&self) -> &dyn ModelTracker

The implementation should return a reference to its ModelNotify field.

fn as_any(&self) -> &dyn Any

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

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

Returns an iterator visiting all elements of the model.

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

fn eq(&self, other: &Self) -> 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 !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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

type Error = ()

The type returned in the event of a conversion error.

fn try_into(self) -> Result<Rc<dyn Model<Data = T>>, Self::Error>

Performs the conversion.
