Struct slint::ModelRc

pub struct ModelRc<T>(_);
Expand description

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>.

Converts to this type from the input type.
Converts to this type from the input type.
The model data: A model is a set of row and each row has this data
The amount of row in the model
Returns the data for a particular row. This function should be called with row < row_count(). Read more
Sets the data for a particular row. Read more
The implementation should return a reference to its ModelNotify field. Read more
Return something that can be downcastโ€™ed (typically self) Read more
Returns an iterator visiting all elements of the model.
This method tests for self and other values to be equal, and is used by ==.
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
The type returned in the event of a conversion error.
Performs the conversion.

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Anyโ€™s vtable from &Traitโ€™s.
Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Anyโ€™s vtable from &mut Traitโ€™s.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

Convenience function that calls ModelTracker::track_row_data_changes before returning Model::row_data. Read more
Returns a new Model where all elements are mapped by the function map_function. This is a shortcut for MapModel::new().
Returns a new Model where the elements are filtered by the function filter_function. This is a shortcut for FilterModel::new().
Returns a new Model where the elements are sorted ascending. This is a shortcut for SortModel::new_ascending().
Returns a new Model where the elements are sorted by the function sort_function. This is a shortcut for SortModel::new().
