Struct SortBy

Source
pub struct SortBy<S, F>{ /* private fields */ }
Expand description

A VectorDiff stream adapter that presents a sorted view of the underlying ObservableVector items.

Sorting is done using a custom comparison function. Otherwise this adapter works exactly like Sort, see that type’s documentation for details on how this adapter operates.

Implementations§

Source§

impl<S, F> SortBy<S, F>

Source

pub fn new( initial_values: Vector<VectorDiffContainerStreamElement<S>>, inner_stream: S, compare: F, ) -> (Vector<VectorDiffContainerStreamElement<S>>, Self)

Create a new SortBy with the given (unsorted) initial values, stream of VectorDiff updates for those values, and the comparison function.

Trait Implementations§

Source§

impl<S, F> Stream for SortBy<S, F>

Source§

type Item = <S as Stream>::Item

Source§

fn poll_next( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Option<Self::Item>>
