Enum JsonValidatedLimit 

#[non_exhaustive]
pub enum JsonValidatedLimit {
    ValueAndKeyNodes,
    EncodedStringBytes,
}

Identifies an additional per-document decode limit for validated JSON.

The decoder reports this value in JsonValidatedDecodeError::Limit when a configured value or encoded-string bound is exceeded.

Examples

use std::convert::Infallible;

use qubit_json::decode::JsonDecoder;
use qubit_json::decode::JsonNumberPolicy;
use qubit_json::decode::JsonValidatedDecodeError;
use qubit_json::decode::JsonValidatedDecodeOptions;
use qubit_json::decode::JsonValidatedLimit;

let options = JsonValidatedDecodeOptions::builder()
    .max_value_and_key_nodes(2)
    .build();
let error = JsonDecoder::unlimited()
    .decode_unique_validated_str("{\"key\":1}", &options, |_, _| {
        Ok::<_, Infallible>(JsonNumberPolicy::Preserve)
    })
    .expect_err("the object, key, and value exceed the two-node limit");
assert!(matches!(
    error,
    JsonValidatedDecodeError::Limit {
        limit: JsonValidatedLimit::ValueAndKeyNodes,
        ..
    }
));

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ValueAndKeyNodes

Value entries plus decoded object-key entries.

EncodedStringBytes

Source bytes inside one encoded string token, excluding quotes.
