resolv.conf

解析 /etc/resolv.conf 文件。

use unixism::dns;

fn main() {
    let config = dns::resolv::parse_default().unwrap();

    for nameserver in config.nameservers {
        println!("{}", nameserver.to_string());
    }

    for domain in config.search_domains {
        println!("{domain}");
    }

    for option in config.options {
        match option {
            dns::resolv::ConfigOption::Timeout(timeout) => {
                println!("timeout: {timeout}");
            }
            _ => {}
        }
    }
}

解析任何类型的 io::Read 类型。

use std::fs;
use unixism::dns;

fn main() {
    let config = dns::resolv::parse(fs::File::open("local.conf").unwrap()).unwrap();

    for nameserver in config.nameservers {
        println!("{}", nameserver.to_string());
    }

    for domain in config.search_domains {
        println!("{domain}");
    }

    for option in config.options {
        match option {
            dns::resolv::ConfigOption::Timeout(timeout) => {
                println!("timeout: {timeout}");
            }
            _ => {}
        }
    }
}

hosts

解析 /etc/hosts 文件。

use unixism::hosts;

fn main() {
    for host in hosts::parse_default().unwrap() {
        println!("ip: {}, names: {:#?}", host.ip, host.names);
    }
}

解析任何类型的 io::Read 类型。

use std::fs;
use unixism::hosts;

fn main() {
    for host in hosts::parse(fs::File::open("local.conf").unwrap()).unwrap() {
        println!("ip: {}, names: {:#?}", host.ip, host.names);
    }
}
