Trait Storage

pub trait Storage<T>: Sized {
    type Output;

    // Required methods
    fn insert(&mut self, index: usize, item: T);
    fn finish(self, pushed: usize) -> Result<Self::Output, Self>;

Backing storage for pull operations

Required Associated Types

type Output

Required Methods

fn insert(&mut self, index: usize, item: T)

Insert an item into a storage slot

index is the index of this push operation since the call to Consumer::try_recv_*.

fn finish(self, pushed: usize) -> Result<Self::Output, Self>

Called to seal the storage after all negociated items have been received

The negociated number of items is available as pushed.

Provided Methods

fn reserve(&mut self, len: usize)

Pre-allocate space for len additional items

fn bounds(&self) -> (Option<usize>, Option<usize>)

Specify the number of items that this storage can handle

The value must be returned as (minimum, maximum).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
