Struct JsonBytesValueDecoder 

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

Decodes JSON bytes into one owned value via serde_json. Its stateless marker implements Clone, Copy, and Default without requiring those traits on T.

Type Parameters

• T: Target value type deserialized through Serde.

Examples

use qubit_codec::{JsonBytesValueDecoder, ValueDecoder};
use serde::Deserialize;

#[derive(Debug, Deserialize, PartialEq)]
struct Point {
    x: i32,
    y: i32,
}

let mut decoder = JsonBytesValueDecoder::<Point>::new();
let point = decoder.decode(br#"{"x":1,"y":2}"#).unwrap();
assert_eq!(point, Point { x: 1, y: 2 });

Implementations

impl<T> JsonBytesValueDecoder<T>

pub const fn new() -> Self

Creates a JSON bytes decoder for values of type T.

Returns

Returns a stateless decoder without allocating or constructing a T.

Trait Implementations

impl<T> Clone for JsonBytesValueDecoder<T>

fn clone(&self) -> Self

Returns an identical stateless decoder without requiring T: Clone.

Returns

Returns a decoder associated with the same target type.

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

Performs copy-assignment from source.

impl<T> Copy for JsonBytesValueDecoder<T>

impl<T: Debug> Debug for JsonBytesValueDecoder<T>

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

Formats the value using the given formatter.

impl<T> Default for JsonBytesValueDecoder<T>

fn default() -> Self

Creates a decoder for T without constructing a value of that type.

Returns

Returns an uninitialized stateless decoder associated with T.

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

where T: DeserializeOwned,

type Error = Error

JSON syntax 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 using serde_json::from_slice.

Parameters

• input: One complete JSON value, optionally surrounded by whitespace. String-content validation follows T’s Serde deserialization implementation.

Returns

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

Errors

Returns a JSON error for malformed or incomplete input, trailing non-whitespace data, or a value incompatible with T. Validation follows serde_json and T’s Deserialize implementation; byte-oriented targets may accept non-UTF-8 string contents.
