egzreader

在Rust中轻松读取gzip和非gzip流。

安装

# Cargo.toml
[dependencies]
egzreader = "2"

示例

use std::io::prelude::*;
use std::io;
use std::fs::File;
use egzreader::EgzReader;

fn read_hello() -> io::Result<()> {
    // text file
    let mut r1 = EgzReader::new(
        File::open("examples/hello.txt")?
    );
    // gzip encoded text file
    let mut r2 = EgzReader::new(
        File::open("examples/hello.txt.gz")?
    );

    let mut s1 = String::new();
    let mut s2 = String::new();

    r1.read_to_string(&mut s1)?;
    r2.read_to_string(&mut s2)?;

    assert_eq!(s1, "Hello!");
    assert_eq!(s2, "Hello!");

    Ok(())
}

lib.rs:

轻松读取gzip和非gzip流。

EgzReader 当底层读者是gzip流时解码，非gzip时直接读取。

示例

use std::io::prelude::*;
use std::io;
use std::fs::File;
use egzreader::EgzReader;

fn read_hello() -> io::Result<()> {
    // text file
    let mut r1 = EgzReader::new(
        File::open("examples/hello.txt")?
    );
    // gzip encoded text file
    let mut r2 = EgzReader::new(
        File::open("examples/hello.txt.gz")?
    );

    let mut s1 = String::new();
    let mut s2 = String::new();

    r1.read_to_string(&mut s1)?;
    r2.read_to_string(&mut s2)?;

    assert_eq!(s1, "Hello!");
    assert_eq!(s2, "Hello!");

    Ok(())
