Struct JsonOptimizer 

pub struct JsonOptimizer;

JSON optimization utilities for reducing payload sizes and improving performance.

This struct provides methods for optimizing JSON payloads by removing unnecessary fields, compressing data, and minimizing payload sizes while maintaining functionality.

Implementations

impl JsonOptimizer

pub fn optimize_request_payload(json: &Value) -> Value

Optimize JSON payload by removing unnecessary fields and minimizing size.

This method recursively processes JSON objects and arrays to remove null values, empty arrays, and optimize the structure for smaller payload sizes while maintaining data integrity.

Arguments

• json - The JSON value to optimize

Returns

Returns an optimized JSON value with reduced size.

Examples

use ultrafast_gateway::json_optimization::JsonOptimizer;
use serde_json::json;

let original = json!({
    "model": "gpt-4",
    "messages": [{"role": "user", "content": "Hello"}],
    "unnecessary_field": null,
    "empty_array": []
});

let optimized = JsonOptimizer::optimize_request_payload(&original);
// Result: {"model": "gpt-4", "messages": [{"role": "user", "content": "Hello"}]}

pub fn create_minimal_response(data: &Value) -> Value

Create a minimal JSON response with only essential fields.

This method creates a standardized minimal response structure that contains only the essential data field, reducing response size and improving parsing performance.

Arguments

• data - The data to include in the response

Returns

Returns a minimal JSON response structure.

Examples

use ultrafast_gateway::json_optimization::JsonOptimizer;
use serde_json::json;

let data = json!({"result": "success"});
let response = JsonOptimizer::create_minimal_response(&data);
// Result: {"data": {"result": "success"}}

pub fn optimize_chat_request(request: &Value) -> Value

Optimize chat completion request by removing unnecessary fields.

This method specifically optimizes chat completion requests by keeping only the essential fields required for the API call, removing any unnecessary or null fields to reduce payload size.

Arguments

• request - The chat completion request to optimize

Returns

Returns an optimized chat completion request with only essential fields.

Examples

use ultrafast_gateway::json_optimization::JsonOptimizer;
use serde_json::json;

let request = json!({
    "model": "gpt-4",
    "messages": [{"role": "user", "content": "Hello"}],
    "temperature": 0.7,
    "max_tokens": 100,
    "unnecessary_field": null,
    "extra_config": {}
});

let optimized = JsonOptimizer::optimize_chat_request(&request);
// Keeps only: model, messages, temperature, max_tokens, etc.

pub fn optimize_embedding_request(request: &Value) -> Value

Optimize embedding request by removing unnecessary fields.

This method specifically optimizes embedding requests by keeping only the essential fields required for the embedding API call, removing any unnecessary or null fields to reduce payload size.

Arguments

• request - The embedding request to optimize

Returns

Returns an optimized embedding request with only essential fields.

Examples

use ultrafast_gateway::json_optimization::JsonOptimizer;
use serde_json::json;

let request = json!({
    "model": "text-embedding-ada-002",
    "input": "Hello world",
    "encoding_format": "float",
    "dimensions": 1536,
    "unnecessary_field": null
});

let optimized = JsonOptimizer::optimize_embedding_request(&request);
// Keeps only: model, input, encoding_format, dimensions

pub fn compress_json(json: &Value) -> Value

Compress JSON by using shorter field names where possible

pub fn decompress_json(json: &Value) -> Value

Decompress JSON by restoring original field names

pub fn calculate_payload_size(json: &Value) -> usize

Calculate JSON payload size in bytes

pub fn get_size_reduction(original: &Value, optimized: &Value) -> f64

Get payload size reduction percentage
