Struct DuplicateKeyRejectingJsonValueSeed 

pub struct DuplicateKeyRejectingJsonValueSeed;

Serde seed that constructs a DuplicateKeyRejectingJsonValue.

Use this seed when the caller owns a deserializer and needs duplicate-key rejection without requiring an intermediate typed wrapper.

Native i64, u64, and finite f64 events retain their numeric representation. If an upstream deserializer exposes an arbitrary-precision number as map events, this seed treats those events as an ordinary object because it cannot determine their provenance. Lexical admission by crate::decode::JsonDecoder does not change the subsequent Serde event representation. See DuplicateKeyRejectingJsonValue for the corresponding wrapper behavior and doc/number_contract.md in the repository for the numeric contract. For complete JSON input with native numeric events across feature unification, use crate::decode::JsonDecoder::decode_unique_seed_utf8.

Examples

use qubit_json::value::DuplicateKeyRejectingJsonValueSeed;
use serde::de::DeserializeSeed;

let mut deserializer = serde_json::Deserializer::from_str(r#"{"ok":true}"#);
let value = DuplicateKeyRejectingJsonValueSeed::new().deserialize(&mut deserializer)?;
assert_eq!(value.into_inner()["ok"], true);

Implementations

impl DuplicateKeyRejectingJsonValueSeed

pub const fn new() -> Self

Creates a seed that rejects duplicate keys in every decoded object.

Returns

A reusable stateless duplicate-key-rejecting JSON value seed.

Trait Implementations

impl Clone for DuplicateKeyRejectingJsonValueSeed

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DuplicateKeyRejectingJsonValueSeed

impl Debug for DuplicateKeyRejectingJsonValueSeed

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

Formats the value using the given formatter.

impl Default for DuplicateKeyRejectingJsonValueSeed

fn default() -> Self

Returns the “default value” for a type.

impl<'de> DeserializeSeed<'de> for DuplicateKeyRejectingJsonValueSeed

type Value = DuplicateKeyRejectingJsonValue

The owned JSON value produced after duplicate keys are rejected.

fn deserialize<D>(self, deserializer: D) -> Result<Self::Value, D::Error>

where D: Deserializer<'de>,

Deserializes one JSON value with recursive duplicate-key rejection.

Returns

The materialized JSON value after every object has passed duplicate-key validation.

Errors

Returns the deserializer’s error if it cannot decode the value or if any object contains a duplicate key.

Type Parameters

• D is the deserializer that supplies the value’s Serde events.

Parameters

• deserializer supplies the value to decode. Object entries are checked recursively for duplicate keys.
