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>.

Construct an empty 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 downcast’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 ==. Read more
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason. Read more
The type returned in the event of a conversion error.
Performs the conversion.
