RawSerde

RawSerde 是一个序列化库，允许对非引用类型进行原始序列化和反序列化。

示例

Cargo.toml

[dependencies]
raw_serde = "*"

example.rs

extern crate raw_serde;

use raw_serde::*;

#[derive(RawSerialize, RawDeserialize, Debug, PartialEq, Eq)]
struct test_struct {
  x: i32,
  y: i32,
  z: i128
}

fn test() {
  // Create some data
  let mut v = vec![];
  for _ in 0..10 {
    let mut x = HashMap::<String, i32>::new();
    for i in 0..100 {
      x.insert(i.to_string(), i);
    }
  v.push(x);
  }

  // Create a file to read from and write to
  let mut file = OpenOptions::new().read(true).write(true).create(true).open("test_vec.dat").unwrap();

  // Write out vector of hashmaps
  v.raw_serialize(&mut file).unwrap();

  // To read the data back from the file, we have to move the file cursor to where we started writing data,
  // which is at position 0 since we started writing to a new file
  file.seek(SeekFrom::Start(0)).unwrap();

  // Read the data back, unwrap it
  let x = Vec::<HashMap<String, i32>>::raw_deserialize(&mut file).unwrap();
  assert!(x == v)
}
