URI parse based on nom composing parser library.
Provides simple parser that parses URI string into structure optimized for processing - Query is parsed to HashTable, path to Path etc.
Consider this code:
extern crate hyper;
extern crate uri_parser;
use uri_parser::parse_uri;
use std::time::{Duration, SystemTime};
use hyper::Uri;
use std::str::FromStr;
fn dur_f64(d: Duration) -> f64 {
d.as_secs() as f64 + d.subsec_nanos() as f64 / 1e9
}
fn main() {
let count = 1_000_000;
let a_uri = "http://www.example.com/root/test?kulo=sak&kde=je&help=no&usi=yes#middle";
let start = SystemTime::now();
for _i in 0..count {
let u = parse_uri(a_uri).unwrap();
let d = u.query.unwrap();
let h=d.get("help").unwrap();
assert_eq!(*h, "no");
}
let dur = start.elapsed().unwrap();
println!("{} loops of my parse_uri took {} secs", count, dur_f64(dur));
let start = SystemTime::now();
for _i in 0..count {
let u = Uri::from_str(a_uri).unwrap();
let q = u.query().unwrap();
for qi in q.split("&") {
let kv: Vec<_> = qi.split("=").collect();
if kv[0] == "help" {
let h = kv[1];
assert_eq!(h, "no");
}
}
}
let dur = start.elapsed().unwrap();
println!("{} loops of hyper from_str took {} secs", count, dur_f64(dur));
}
This library will perform better as query string is already in HashMap:
1000000 loops of my parse_uri took 0.900562534 secs
1000000 loops of hyper from_str took 1.136823832 secs
Limitations:
- Parses only absolute URIs
- Will not parse IP6 host (yet)
- No decoding of URL encoded strings (%hexa) - because it's referring original string
- Will not work well with malformed URI, only very basic parsing errors handling
