Trait VecJsonExt

pub trait VecJsonExt {
    // Required method
    fn parse_json(self) -> Result<OwnedValue>;
}

Extension trait for Vec<u8> to add zero-allocation JSON parsing

This trait provides optimized JSON parsing for Vec<u8> by taking ownership and parsing in-place using SIMD-accelerated parsing, eliminating intermediate allocations.

Usage

use rusty_feeder::exchange::zerocopy_helpers::VecJsonExt;

let json_data = r#"{"symbol":"BTC/USD","price":50000.0}"#.as_bytes().to_vec();
let parsed = json_data.parse_json()?;
assert_eq!(parsed["symbol"], "BTC/USD");

See module-level documentation for detailed performance characteristics and HFT optimization guidelines.

Required Methods

fn parse_json(self) -> Result<OwnedValue>

Parse JSON from a Vec<u8> with zero allocation

Takes ownership of the vector and parses the JSON in-place using SIMD-accelerated parsing. This is the most efficient method for parsing JSON from owned byte data.

Arguments

• self - The Vec<u8> containing UTF-8 encoded JSON data (consumed)

Returns

• Ok(OwnedValue) - Successfully parsed JSON value
• Err(anyhow::Error) - Parse error with detailed error information

Performance

• Zero memory allocations for the parsing operation
• SIMD-accelerated parsing (2-10x faster than standard parsers)
• In-place mutation of the input buffer for optimal cache usage

Examples

use rusty_feeder::exchange::zerocopy_helpers::VecJsonExt;

let json_data = r#"{"symbol":"BTC/USD","price":50000.0}"#.as_bytes().to_vec();
let parsed = json_data.parse_json()?;
assert_eq!(parsed["symbol"], "BTC/USD");
