Struct differential_dataflow::trace::implementations::containers::SliceContainer

pub struct SliceContainer<B> { /* private fields */ }

A container that accepts slices [B::Item].

Trait Implementations

impl<B> BatchContainer for SliceContainer<B>

where B: Ord + Clone + Sized + 'static,

type PushItem = Vec<B>

The type of contained item.

type ReadItem<'a> = &'a [B]

The type that can be read back out of the container.

fn push(&mut self, item: Vec<B>)

Inserts an owned item.

fn copy_push(&mut self, item: &Vec<B>)

Inserts an owned item.

fn copy(&mut self, item: Self::ReadItem<'_>)

Inserts a borrowed item.

fn copy_range(&mut self, other: &Self, start: usize, end: usize)

Extends from a range of items in anotherSelf.

fn with_capacity(size: usize) -> Self

Creates a new container with sufficient capacity.

fn merge_capacity(cont1: &Self, cont2: &Self) -> Self

Creates a new container with sufficient capacity.

fn index(&self, index: usize) -> Self::ReadItem<'_>

Reference to the element at this position.

fn len(&self) -> usize

Number of contained elements

fn last(&self) -> Option<Self::ReadItem<'_>>

Returns the last item if the container is non-empty.

fn is_empty(&self) -> bool

Indicates if the length is zero.

fn advance<F: for<'a> Fn(Self::ReadItem<'a>) -> bool>( &self, start: usize, end: usize, function: F ) -> usize

Reports the number of elements satisfing the predicate.

impl<B> Default for SliceContainer<B>

Default implementation introduces a first offset.

fn default() -> Self

Returns the “default value” for a type.
