core:json_nsd
JSON NSD (Non-Self-Describing) serialization and deserialization.
Structs are encoded as positional arrays (field names omitted).
Unit variants (enums) are encoded as integer discriminants.
Payload variants are encoded as [disc, payload].
Synopsis
struct Point {
x: i32,
y: i32,
}
impl Serialize for Point;
impl Deserialize for Point;
assert to_string(&Point { x: 1, y: 2 }) matches { Ok(s) && s == "[1,2]" };
assert from_string::<Point>("[1,2]") matches { Ok(p) && p.x == 1 && p.y == 2 };
Functions
pub fn to_bytes<T: Serialize>(value: &T) -> Result<List<u8>, SerializeError>
Serializes a value to UTF-8 JSON NSD bytes — the primary entry point.
pub fn to_string<T: Serialize>(value: &T) -> Result<String, SerializeError>
Serializes a value to a JSON NSD string. Convenience over to_bytes for
text contexts; serde I/O is bytes-primary.
pub fn from_string<T: Deserialize>(input: String) -> Result<T, DeserializeError>
Deserializes a value from a JSON NSD string.
pub fn from_bytes<T: Deserialize, S: AsByteSlice>(input: S) -> Result<T, DeserializeError>
Deserializes a value from UTF-8 JSON NSD bytes — the primary entry point.
Accepts any byte source via AsByteSlice (including a String).
