Trait Implementations

impl Archive for QueryBookResponse

where CorrelationId: Archive, u32: Archive, i64: Archive, u64: Archive,

type Archived = ArchivedQueryBookResponse

The archived representation of this type.

type Resolver = QueryBookResponseResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

unsafe fn resolve( &self, pos: usize, resolver: Self::Resolver, out: *mut Self::Archived, )

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for QueryBookResponse

fn clone(&self) -> QueryBookResponse

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for QueryBookResponse

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<__D: Fallible + ?Sized> Deserialize<QueryBookResponse, __D> for Archived<QueryBookResponse>

where CorrelationId: Archive, Archived<CorrelationId>: Deserialize<CorrelationId, __D>, u32: Archive, Archived<u32>: Deserialize<u32, __D>, i64: Archive, Archived<i64>: Deserialize<i64, __D>, u64: Archive, Archived<u64>: Deserialize<u64, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<QueryBookResponse, __D::Error>

Deserializes using the given deserializer

impl RingKernelHandler<QueryBookRing, QueryBookResponse> for OrderMatchingEngine

Ring kernel handler for book queries.

fn handle<'life0, 'life1, 'async_trait>( &'life0 self, _ctx: &'life1 mut RingContext<'_>, msg: QueryBookRing, ) -> Pin<Box<dyn Future<Output = KernelResult<QueryBookResponse>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Handle an incoming message.

fn initialize<'life0, 'life1, 'async_trait>( &'life0 self, _ctx: &'life1 mut RingContext<'_>, ) -> Pin<Box<dyn Future<Output = Result<(), KernelError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: Sync + 'async_trait,

Initialize the kernel state.

fn shutdown<'life0, 'life1, 'async_trait>( &'life0 self, _ctx: &'life1 mut RingContext<'_>, ) -> Pin<Box<dyn Future<Output = Result<(), KernelError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: Sync + 'async_trait,

Called when the kernel is being shut down.

impl RingMessage for QueryBookResponse

fn message_type() -> u64

Get the message type discriminator.

fn message_id(&self) -> MessageId

Get the message ID.

fn correlation_id(&self) -> CorrelationId

Get the correlation ID (if any).

fn priority(&self) -> Priority

Get the priority.

fn serialize(&self) -> Vec<u8>

Serialize the message to bytes.

fn deserialize(bytes: &[u8]) -> Result<Self>

where Self: Sized,

Deserialize a message from bytes.

fn size_hint(&self) -> usize

Get the serialized size hint.

impl<__S: Fallible + ?Sized> Serialize<__S> for QueryBookResponse

where CorrelationId: Serialize<__S>, u32: Serialize<__S>, i64: Serialize<__S>, u64: Serialize<__S>,

fn serialize(&self, serializer: &mut __S) -> Result<Self::Resolver, __S::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
