Struct JsonValidatedDecodeOptionsBuilder 

pub struct JsonValidatedDecodeOptionsBuilder { /* private fields */ }

Builds JsonValidatedDecodeOptions.

Unset optional settings impose no additional limit. A configured zero is a valid bound and permits zero counted nodes or zero source bytes.

Examples

use qubit_json::decode::{JsonDecoder, JsonNumberPolicy, JsonValidatedDecodeOptions};

let options = JsonValidatedDecodeOptions::builder()
    .max_value_and_key_nodes(3)
    .max_encoded_string_bytes(8)
    .build();
let value = JsonDecoder::unlimited().decode_unique_validated_str(
    r#"{"id":42}"#,
    &options,
    |_path, _token| Ok::<_, std::convert::Infallible>(JsonNumberPolicy::ExactSafeInteger),
)?;
assert_eq!(value.as_value()["id"].as_i64(), Some(42));

Implementations

impl JsonValidatedDecodeOptionsBuilder

pub fn admission_policy(self, policy: JsonValidatedAdmissionPolicy) -> Self

Selects the token admission order for validated decoding.

Parameters

• policy - The admission order to use.

Returns

The builder configured with the selected admission policy.

pub fn root_kind(self, kind: JsonRootKind) -> Self

Requires a particular root kind.

Parameters

• kind - Root kind required for a successfully decoded document.

Returns

The builder configured with the required root kind.

pub fn number_model(self, model: JsonDecodeNumberModel) -> Self

Selects the number representation model.

Parameters

• model - Number representation model used when numbers are preserved.

Returns

The builder configured with the selected number model.

pub fn max_value_and_key_nodes(self, maximum: usize) -> Self

Limits value entries and decoded object-key entries per document.

Every JSON value counts once, and every object key also counts once. Zero is a valid limit and permits no counted entries.

Parameters

• maximum - Maximum combined value and object-key node count.

Returns

The builder with this per-document limit configured.

pub fn max_encoded_string_bytes(self, maximum: usize) -> Self

Limits the source bytes inside each string token, excluding quotes. Escape spelling is counted as it appears in the source, so \u0061 consumes six bytes. Zero permits only empty string token contents.

Parameters

• maximum - Maximum number of source bytes inside each string token.

Returns

The builder with this per-token limit configured.

pub fn build(self) -> JsonValidatedDecodeOptions

Builds the configured options.

Returns

The options snapshot containing all configured settings.

Trait Implementations

impl Clone for JsonValidatedDecodeOptionsBuilder

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

Performs copy-assignment from source.

impl Debug for JsonValidatedDecodeOptionsBuilder

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

Formats the value using the given formatter.

impl Default for JsonValidatedDecodeOptionsBuilder

fn default() -> Self

Returns the “default value” for a type.
