pub struct VecPush<Buf> { /* private fields */ }

Available on crate feature alloc only.

Terminal push operator that collects items into a Vec.

Uses Push::size_hint to pre-allocate capacity via Vec::reserve.

Trait Implementations

impl<Buf, Item, Meta> Push<Item, Meta> for VecPush<Buf>

where Buf: BorrowMut<Vec<Item>>, Meta: Copy,

type Ctx<'ctx> = ()

The context type required to push into this pipeline.

type CanPend = Infallible

Whether this push can return PushStep::Pending.

fn poll_ready( self: Pin<&mut Self>, _ctx: &mut Self::Ctx<'_>, ) -> PushStep<Self::CanPend>

Check if this push is ready to accept an item.

fn start_send(self: Pin<&mut Self>, item: Item, _meta: Meta)

Send an item into this push pipeline.

fn poll_flush( self: Pin<&mut Self>, _ctx: &mut Self::Ctx<'_>, ) -> PushStep<Self::CanPend>

Flushes any buffered items in this push pipeline.

fn size_hint(self: Pin<&mut Self>, hint: (usize, Option<usize>))

Informs this push how many items are about to be sent.
