我一直在寻找加速基本的Python函数,它基本上只需要一行文本并检查子行的行.Python程序如下:

import time

def fun(line):
    l = line.split(" ", 10)
    if 'TTAGGG' in l[9]:
        pass  # Do nothing

line = "FCC2CCMACXX:4:1105:10758:14389# 81 chrM 1 32 10S90M = 16151 16062 CATCACGATGGATCACAGGTCTATCACCCTATTAACCACTCACGGGAGCTTTCCATGCATTTGGTATTTTCGTCTGGGGGGTGTGCACGCTTAGGGGATAGCATTG bbb^Wcbbbbccbbbcbccbba]WQG^bbcdcb_^_c_^`ccdddeeeeeffggggiiiiihiiiiihiiihihiiiihghhiihgfgfgeeeeebbb NM:i:1 AS:i:85 XS:i:65 RG:Z:1_DB31"

time0 = time.time()
for i in range(10000):
    fun(line)
print time.time() - time0

我想看看是否可以使用Rust的一些高级功能来获得一些性能,但代码运行速度要慢得多.Rust转换是:

extern crate regex;
extern crate time;
use regex::Regex;

fn main() {
    let line = "FCC2CCMACXX:4:1105:10758:14389# 81 chrM 1 32 10S90M = 16151 16062 CATCACGATGGATCACAGGTCTATCACCCTATTAACCACTCACGGGAGCTTTCCATGCATTTGGTATTTTCGTCTGGGGGGTGTGCACGCTTAGGGGATAGCATTG bbb^Wcbbbbccbbbcbccbba]WQG^bbcdcb_^_c_^`ccdddeeeeeffggggiiiiihiiiiihiiihihiiiihghhiihgfgfgeeeeebbb NM:i:1 AS:i:85 XS:i:65 RG:Z:1_DB31";    
    let substring: &str …
