# 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](https://github.com/Stenway/RSV-Specification)
### example
```rust
use rsv_core::reader::Reader;
use rsv_core::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());
}
```
