Struct JsonBytesValueCodec 

pub struct JsonBytesValueCodec<T> { /* private fields */ }

Encodes and decodes one serializable value through UTF-8 JSON bytes.

This type combines JsonBytesValueEncoder and JsonBytesValueDecoder for registry-backed or bidirectional call sites. It holds no state between calls, so it is Copy and Default, and encoding and decoding can share one value through ValueEncoder and ValueDecoder.

Type Parameters

• T: Value type serialized to JSON bytes and recovered from them.

Examples

use qubit_codec::JsonBytesValueCodec;
use qubit_codec::ValueDecoder;
use qubit_codec::ValueEncoder;

let mut codec = JsonBytesValueCodec::<String>::new();
assert_eq!(codec.encode(&"hello".to_string()).unwrap(), br#""hello""#.to_vec());
assert_eq!(codec.decode(br#""hello""#).unwrap(), "hello");

Implementations

impl<T> JsonBytesValueCodec<T>

pub const fn new() -> Self

Returns

Returns a stateless codec bound to values of type T.
