pbuf

从/向实现了 protobuf 读写操作的任何东西进行读写...

示例假设 Msg 是您的 protobuf，msg.rs 是它所在的位置，有关如何从 .proto 文件生成 .rs 的信息，请参阅 rust-protobuf。

添加到 Cargo.toml

pbuf = "0.3.2"

读取示例

extern crate pbuf;
extern crate protobuf;

use std::io::prelude::*;
use std::io::{BufReader, self};
use std::fs::File;

mod msg;
use msg::Msg;

use pbuf::read_pbuf;

let mut reader = Box::new(BufReader::new(io::stdin()));
// To read from file
// let mut reader = Box::new(BufReader::new(File::open  (&<file pointer>).unwrap()))

// Reads entire buffer and fill
let mut msgs: Vec<Msg> = read_pbuf(&mut reader);

写入示例

extern crate pbuf;
extern crate protobuf;

use std::io::prelude::*;
use std::io::{BufWriter, self};
use std::fs::File;

mod msg;
use msg::Msg;

use pbuf::write_pbuf;

let mut writer = Box::new(BufWriter::new(io::stdout()));
// To write to file
// let mut writer = Box::new(BufWriter::new(File::create(&<file pointer>).unwrap()))

for msg in msgs.iter() {
    write_pbuf(msg, &mut writer);
  }
