Struct JsonStringValueEncoder 

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

Encodes one serializable value into a UTF-8 JSON string via serde_json. Its stateless marker implements Clone, Copy, and Default without requiring those traits on T.

Type Parameters

• T: Source value type serialized through Serde.

Examples

use qubit_codec::{JsonStringValueEncoder, ValueEncoder};
use serde::Serialize;

#[derive(Serialize)]
struct Point {
    x: i32,
    y: i32,
}

let mut encoder = JsonStringValueEncoder::<Point>::new();
let json = encoder.encode(&Point { x: 1, y: 2 }).unwrap();
assert_eq!(json, r#"{"x":1,"y":2}"#);

Implementations

impl<T> JsonStringValueEncoder<T>

pub const fn new() -> Self

Creates a JSON string encoder for values of type T.

Returns

Returns a stateless encoder without allocating an output string.

Trait Implementations

impl<T> Clone for JsonStringValueEncoder<T>

fn clone(&self) -> Self

Copies the stateless encoder marker without requiring T: Clone.

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

Performs copy-assignment from source.

impl<T> Copy for JsonStringValueEncoder<T>

impl<T: Debug> Debug for JsonStringValueEncoder<T>

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

Formats the value using the given formatter.

impl<T> Default for JsonStringValueEncoder<T>

fn default() -> Self

Creates the stateless encoder through its const constructor.

impl<T> ValueEncoder<T> for JsonStringValueEncoder<T>

where T: Serialize,

type Error = Error

JSON serialization error returned when T cannot be serialized.

type Output = String

UTF-8 JSON text owned by the caller.

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

Serializes input into a compact JSON string.

Parameters

• input: Value to serialize.

Returns

The serialized JSON text as an owned UTF-8 string.

Errors

Returns the serde_json error if serialization fails, such as when a custom serializer reports an error or the value contains unsupported data.
