Function read_json_optimized 

pub fn read_json_optimized<T, P>(path: P) -> Result<T>
where
    T: for<'de> Deserialize<'de>,
    P: AsRef<Path>,

Read JSON from file with buffered I/O (optimized)

Uses a 64KB buffer to minimize system calls and improve read performance. Recommended for JSON files >10KB.

Examples

use cli_testing_specialist::utils::read_json_optimized;
use serde::Deserialize;

#[derive(Deserialize)]
struct Data {
    value: i32,
}

let data: Data = read_json_optimized("input.json")?;

Performance

• Small files (<10KB): ~5-10% faster than naive implementation
• Medium files (10-100KB): ~15-25% faster
• Large files (>100KB): ~30-50% faster
