Examples

Serialization

use serde_cs::vec::CS;
type Csu32 = CS<u32>;

let cs: Csu32 = CS(vec![]);
let s = serde_json::to_string(&cs).unwrap();
assert_eq!(s, r#""""#);

let cs: Csu32 = CS(vec![1]);
let s = serde_json::to_string(&cs).unwrap();
assert_eq!(s, r#""1""#);

let cs: Csu32 = CS(vec![1, 2, 3]);
let s = serde_json::to_string(&cs).unwrap();
assert_eq!(s, r#""1,2,3""#);

Deserialization

use serde_cs::vec::CS;
type Csu32 = CS<u32>;

let s = r#""""#;
let CS(cs): Csu32 = serde_json::from_str(s).unwrap();
assert_eq!(cs, vec![0u32; 0]);

let s = r#"",,,,""#;
let CS(cs): Csu32 = serde_json::from_str(s).unwrap();
assert_eq!(cs, vec![0u32; 0]);

let s = r#"",,1,,,,,""#;
let CS(cs): Csu32 = serde_json::from_str(s).unwrap();
assert_eq!(cs, vec![1]);

let s = r#"",,1,,,2,,,,""#;
let CS(cs): Csu32 = serde_json::from_str(s).unwrap();
assert_eq!(cs, vec![1, 2]);

let s = r#"",,1,,,a,,,,""#;
let res: Result<Csu32, _> = serde_json::from_str(s);
assert!(res.is_err());
