Struct WsBookUpdateProcessor 

pub struct WsBookUpdateProcessor { /* private fields */ }

In-place WS book message processor built on simd-json’s tape API.

This avoids building a DOM (which allocates for arrays/objects) by decoding into a reusable tape, then traversing it to extract the fields needed for order book updates.

Implementations

impl WsBookUpdateProcessor

pub fn new(input_len_hint: usize) -> Self

Create a new processor.

input_len_hint should be set to the typical WS message size to reduce warmup reallocs.

pub fn process_bytes( &mut self, bytes: &mut [u8], books: &OrderBookManager, ) -> Result<WsBookApplyStats>

Process a WS payload in-place (bytes will be mutated by the JSON parser).

pub fn process_text( &mut self, text: String, books: &OrderBookManager, ) -> Result<WsBookApplyStats>

Convenience: process an owned text message without allocating an additional buffer.
