Struct ValueWirePayloadV1Seed 

pub struct ValueWirePayloadV1Seed;

Explicit Serde seed for decoding one unversioned V1 payload.

Use this seed with a decoder that enforces the resource limits appropriate for the surrounding document. For complete JSON input, prefer the bounded JSON decode helpers on ValueWirePayloadV1.

This generic Serde seed preserves the surrounding deserializer’s error semantics; its diagnostics may contain input-derived text. Bounded helpers map target-deserialization failures to InvalidJson metadata containing only the Serde category and location. Resource limits do not sanitize diagnostics, and reader or writer I/O sources may contain application-defined details that require the application’s logging policy.

Examples

With the json feature, use it when the surrounding protocol owns the version envelope and its decoder session:

use qubit_budget::json::{JsonDecodeLimits, JsonDecodeSession};
use qubit_json::decode::JsonDecoder;
use qubit_value::ValueWirePayloadV1Seed;

let limits = JsonDecodeLimits::builder().max_input_bytes(256usize).build();
let session = JsonDecodeSession::from_limits(limits);
let mut decoder = JsonDecoder::new(session);
let payload = decoder.decode_unique_seed_utf8(
    ValueWirePayloadV1Seed::new(),
    br#"{"scalar":{"int32":7}}"#,
)?;
assert_eq!(payload.into_container().data_type(), qubit_datatype::DataType::Int32);

Implementations

impl ValueWirePayloadV1Seed

pub const fn new() -> Self

Creates a seed for one unversioned V1 payload.

Returns

A stateless seed to pass to the surrounding protocol’s deserializer.

Trait Implementations

impl Clone for ValueWirePayloadV1Seed

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 ValueWirePayloadV1Seed

impl Debug for ValueWirePayloadV1Seed

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

Formats the value using the given formatter.

impl Default for ValueWirePayloadV1Seed

fn default() -> Self

Returns the “default value” for a type.

impl<'de> DeserializeSeed<'de> for ValueWirePayloadV1Seed

type Value = ValueWirePayloadV1

Owned scalar-or-collection payload decoded without a version envelope.

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

where D: Deserializer<'de>,

Deserializes one unversioned V1 shape.

Type Parameters

• D - Serde deserializer whose input is valid for 'de and whose resource limits are controlled by the surrounding protocol.

Parameters

• self - Stateless seed consumed by this decoding operation.
• deserializer - Decoder positioned at one unversioned V1 payload.

Returns

An owned payload preserving the decoded scalar or collection shape.

Errors

Propagates D::Error when the input cannot be decoded as a V1 shape, preserving the deserializer’s diagnostics, which may contain input text.
