Struct sixtyfps_corelib::model::VecModel

pub struct VecModel<T> { /* fields omitted */ }

A model backed by a SharedVector

Implementations

impl<T: 'static> VecModel<T>

pub fn from_slice(slice: &[T]) -> ModelHandle<T> where
    T: Clone, 

Allocate a new model from a slice

pub fn push(&self, value: T)

Add a row at the end of the model

pub fn remove(&self, index: usize)

Remove the row at the given index from the model

Trait Implementations

impl<T: Default> Default for VecModel<T>

fn default() -> VecModel<T>

Returns the “default value” for a type.

impl<T> From<Vec<T, Global>> for VecModel<T>

fn from(array: Vec<T>) -> Self

Performs the conversion.

impl<T: Clone + 'static> Model for VecModel<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) -> 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. 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 attach_peer(&self, peer: ModelPeer)

Should forward to the internal ModelNotify::attach

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.
