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