Crate rmp_fs

A small lib that help to serialize and deserialize from/to rmp (RustMessagePack) with a file. It does nothing special, just encapsulates rmp_serde in two functions that can be used repeatedly.

#[macro_use]
extern crate serde_derive;

use rmp_fs::{save_to_rmp, load_from_rmp};
use std::path::Path;

// Define a struct of data
#[derive(Debug, PartialEq, Deserialize, Serialize)]
struct ExampleData {
    value: i64,
    message: String,
}

fn main() {
    let file_name = Path::new("test_rmp_fs.blob");

    let data = ExampleData {
        value: -123456,
        message: "Example rmp_fs".to_string()
    };

    // Save to a file it return Result<(), Box<dyn Error>>
    save_to_rmp(file_name, &data).expect("Fail to save as rmp.");

    // Load from a file it return Result<T, Box<dyn Error>>
    let data2: ExampleData =load_from_rmp(file_name).expect("Fail to load from rmp.");
    println!("{:?}\n{:?}",data,data2);
}

Functions

load_from_rmp	Load RustMessagePack format Deserializable data from a file.
save_to_rmp	Save Serializable data to a file as RustMessagePack format. Note if the file already exist. The existing file is deleted.
