Struct reactive_messaging::prelude::OgreUnique

pub struct OgreUnique<DataType, OgreAllocatorType>where
    DataType: Debug + Send + Sync + 'static,
    OgreAllocatorType: OgreAllocator<DataType> + Send + Sync + 'static,{ /* private fields */ }

Wrapper type for data that requires a custom Drop to be called (through an OgreAllocator). Similar to C++’s unique_ptr

Trait Implementations

impl<DataType, OgreAllocatorType> AsRef<DataType> for OgreUnique<DataType, OgreAllocatorType>where DataType: Debug + Send + Sync, OgreAllocatorType: OgreAllocator<DataType> + Send + Sync,

fn as_ref(&self) -> &DataType

Converts this type into a shared reference of the (usually inferred) input type.

impl<'a, ItemType, OgreAllocatorType, const BUFFER_SIZE: usize, const MAX_STREAMS: usize> ChannelCommon<'a, ItemType, OgreUnique<ItemType, OgreAllocatorType>> for Atomic<'a, ItemType, OgreAllocatorType, BUFFER_SIZE, MAX_STREAMS>where ItemType: Debug + Send + Sync, OgreAllocatorType: OgreAllocator<ItemType> + 'a + Send + Sync,

fn new<IntoString>( name: IntoString ) -> Arc<Atomic<'a, ItemType, OgreAllocatorType, BUFFER_SIZE, MAX_STREAMS>>where IntoString: Into<String>,

Creates a new instance of this channel, to be referred to (in logs) as name

fn flush<'life0, 'async_trait>( &'life0 self, timeout: Duration ) -> Pin<Box<dyn Future<Output = u32> + Send + 'async_trait>>where 'life0: 'async_trait, Atomic<'a, ItemType, OgreAllocatorType, BUFFER_SIZE, MAX_STREAMS>: 'async_trait,

Waits until all pending items are taken from this channel, up until timeout elapses.
Returns the number of still unconsumed items – which is 0 if it was not interrupted by the timeout

fn is_channel_open(&self) -> bool

Tells weather this channel is still enabled to process elements (true before calling the “end stream” / “cancel stream” functions)

fn gracefully_end_stream<'life0, 'async_trait>( &'life0 self, stream_id: u32, timeout: Duration ) -> Pin<Box<dyn Future<Output = bool> + Send + 'async_trait>>where 'life0: 'async_trait, Atomic<'a, ItemType, OgreAllocatorType, BUFFER_SIZE, MAX_STREAMS>: 'async_trait,

Flushes & signals that the given stream_id should cease its activities when there are no more elements left to process, waiting for the operation to complete for up to timeout.
Returns true if the stream ended within the given timeout or false if it is still processing elements.

impl<'a, ItemType, OgreAllocatorType, const BUFFER_SIZE: usize, const MAX_STREAMS: usize> ChannelProducer<'a, ItemType, OgreUnique<ItemType, OgreAllocatorType>> for Atomic<'a, ItemType, OgreAllocatorType, BUFFER_SIZE, MAX_STREAMS>where ItemType: 'a + Send + Sync + Debug, OgreAllocatorType: OgreAllocator<ItemType> + 'a + Send + Sync,

fn send(&self, item: ItemType) -> RetryResult<(), ItemType, (), ()>

Similar to Self::send_with(), but for sending the already-built item.
See there for how to deal with the returned type. IMPLEMENTORS: #[inline(always)]

fn send_with<F>(&self, setter: F) -> RetryResult<(), F, (), ()>where F: FnOnce(&mut ItemType),

Calls setter, passing a slot so the payload may be filled there, then sends the event through this channel asynchronously.
The returned type is conversible to Result<(), F> by calling .into() on it, returning Err<setter> when the buffer is full, to allow the caller to try again; otherwise you may add any retrying logic using the keen-retry crate’s API like in:

fn send_derived(&self, _derived_item: &DerivedItemType) -> bool

For channels that stores the DerivedItemType instead of the ItemType, this method may be useful – for instance: if the Stream consumes Arc<String> (the derived item type) and the channel is for Strings, With this method one may send an Arc directly.
The default implementation, though, is made for types that don’t have a derived item type.

Returns a Stream (and its stream_id) able to receive elements sent through this channel.
If called more than once, each Stream will receive a different element – “consumer pattern”.
