Struct ResponseEncoder 

pub struct ResponseEncoder;

Encoder for the trading wire protocol.

Zero-sized. The runtime owns an Arc<dyn ResponseEncoder<...>>; constructing one is Arc::new(ResponseEncoder).

Trait Implementations

impl Clone for ResponseEncoder

fn clone(&self) -> ResponseEncoder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ResponseEncoder

impl Debug for ResponseEncoder

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

Formats the value using the given formatter.

impl ResponseEncoder for ResponseEncoder

type Report = ExecutionReport

Per-event fan-out report type. Must match crate::Application::Report at the call site.

type Query = QueryResponse

1:1 query response type. Must match crate::Application::QueryResponse at the call site.

fn encode_report( &self, report: &ExecutionReport, buf: &mut [u8], ) -> Result<usize, &'static str>

Encode an application report into buf, returning the number of bytes written. buf is guaranteed by the caller to be large enough for any single response (MAX_RESPONSE_BUF). Returns Err with a static reason on encode failure (the runtime logs at error level and drops the frame; the connection stays open).

fn encode_query( &self, query: &QueryResponse, buf: &mut [u8], ) -> Result<usize, &'static str>

Encode an application query response into buf, returning the number of bytes written. Same buffer-size guarantee and error semantics as Self::encode_report.
