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

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> 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> 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> 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.
