Function with_parser 

pub fn with_parser<F, R>(f: F) -> Result<R, TreeSitterError>
where
    F: FnOnce(&mut RustParser) -> R,

Execute function with pooled parser instance.

On first call per thread, creates new parser. Subsequent calls reuse the same parser instance, avoiding allocation and initialization overhead.

Example

use codex_patcher::pool::with_parser;

let result = with_parser(|parser| {
    parser.parse_with_source("fn main() {}")
})?;
