rsv

an rsv reader and writer crate for Rust.

what is rsv?

rows of string values (rsv) is a modification on the csv format that replaces delimiter characters with unused unicode bytes. This makes encoding and decoding incredibly simple and consistent.

find the specification created by Stenway here

example

use rsv::reader::Reader;
use rsv::writer::Writer;
use serde::{Deserialize, Serialize};


#[derive(Debug, Deserialize, Serialize)]
struct ExampleStruct {
    _num: i32,
    _string: String,
    _option: Option<f64>,
    // _vec_option: Vec<Option<f64>>,
}


fn writer() {
    let mut w = Writer::from_path("basic-serde-example.bin").unwrap();
    let a = ExampleStruct { _num: 30202, _string: "Hello Stenway!".to_string(), _option: None };
    let b = ExampleStruct { _num: -30202, _string: "Hello Stenway!".to_string(), _option: Some(3.14) };


    w.serialize(&a).unwrap();
    w.serialize(&b).unwrap();
}


fn reader() {
    let mut r = Reader::from_path("basic-serde-example.bin").unwrap();


    // If the compiler is unable to implicitly determine the type you may need
    // to explicitly set it.
    let mut r = r.deserialize::<ExampleStruct>();


    println!("{:#?}", r.next().unwrap());
    println!("{:#?}", r.next().unwrap());
    assert!(r.next().is_none());
