pub struct VecModel<T> { /* private fields */ }
Expand description

A model backed by a Vec<T>

Implementations§

§

impl<T> VecModel<T>where T: 'static,

pub fn from_slice(slice: &[T]) -> ModelRc<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 insert(&self, index: usize, value: T)

Inserts a row at position index. All rows after that are shifted. This function panics if index is > row_count().

pub fn remove(&self, index: usize) -> T

Remove the row at the given index from the model

Returns the removed row

pub fn set_vec(&self, new: impl Into<Vec<T, Global>>)

Replace inner Vec with new data

pub fn extend<I>(&self, iter: I)where I: IntoIterator<Item = T>,

Extend the model with the content of the iterator

Similar to Vec::extend

§

impl<T> VecModel<T>where T: Clone + 'static,

pub fn extend_from_slice(&self, src: &[T])

Appends all the elements in the slice to the model

Similar to Vec::extend_from_slice

The amount of row in the model
§

fn row_data(&self, row: usize) -> Option<<VecModel<T> as Model>::Data>

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

impl<T> Downcast for Twhere T: Any,

§

fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>

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.

§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
