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 without requiring those traits on T; 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

Creates a bidirectional JSON bytes codec for values of type T.

Returns

Returns a stateless codec bound to values of type T.

Trait Implementations

impl<T> Clone for JsonBytesValueCodec<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Copy for JsonBytesValueCodec<T>

impl<T: Debug> Debug for JsonBytesValueCodec<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Default for JsonBytesValueCodec<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T> ValueDecoder<[u8]> for JsonBytesValueCodec<T>

where T: DeserializeOwned,

type Error = Error

JSON syntax, UTF-8, or target-value deserialization failure.

type Output = T

Owned value deserialized independently of the input byte slice.

fn decode(&mut self, input: &[u8]) -> Result<Self::Output, Self::Error>

Deserializes input from UTF-8 JSON bytes.

Parameters

• input: One complete UTF-8 JSON value, optionally surrounded by whitespace.

Returns

Returns an owned T; decoding may allocate according to the target type.

Errors

Returns a JSON error for invalid UTF-8, malformed or incomplete input, trailing non-whitespace data, or a value incompatible with T.

impl<T> ValueEncoder<T> for JsonBytesValueCodec<T>

where T: Serialize,

type Error = Error

Serialization failure reported by Serde JSON.

type Output = Vec<u8>

Newly allocated UTF-8 JSON bytes owned by the caller.

fn encode(&mut self, input: &T) -> Result<Self::Output, Self::Error>

Serializes input into UTF-8 JSON bytes.

Parameters

• input: Value borrowed for the duration of serialization.

Returns

Returns a newly allocated vector containing the serialized JSON.

Errors

Returns a JSON error if T rejects serialization or contains a map key that cannot be represented as a JSON object key.
