Trait sixtyfps::Model

pub trait Model {
    type Data;
    fn row_count(&self) -> usize;
    fn row_data(&self, row: usize) -> Self::Data;
    fn attach_peer(&self, peer: ModelPeer);

}

A Model is providing Data for the Repeater or ListView elements of the .60 language

Associated Types

type Data

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

Required methods

fn row_count(&self) -> usize

The amount of row in the model

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

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

fn attach_peer(&self, peer: ModelPeer)

Should forward to the internal ModelNotify::attach

Provided methods

fn set_row_data(&self, _row: usize, _data: Self::Data)

Sets the data for a particular row. This function should be called with row < row_count(). If the model cannot support data changes, then it is ok to do nothing (default implementation). If the model can update the data, it should also call row_changed on its internal ModelNotify.

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

Returns an iterator visiting all elements of the model.
