Struct JSONParser 

pub struct JSONParser {
    pub allow_empty: bool,
    pub strict: bool,
}

Available on crate feature rest and non-WebAssembly only.

JSON parser for application/json content type

Strict Mode

The strict flag controls validation of parsed JSON values:

• strict = true: Rejects non-finite float values (Infinity, -Infinity, NaN)
• strict = false: Allows any valid JSON (but still rejects invalid JSON)

Limitations

Due to serde_json’s adherence to JSON RFC 8259, literal Infinity, -Infinity, and NaN values are not valid JSON and will be rejected during parsing regardless of the strict flag. The strict validation only affects post-parse validation of float values.

In other words:

• Invalid JSON input (e.g., raw Infinity literal) → Always rejected by serde_json
• Valid JSON with non-finite values → Rejected only if strict = true

Fields

allow_empty: bool

Whether to allow empty bodies (returns null)

strict: bool

Whether to enforce strict JSON (reject Infinity, -Infinity, NaN)

Implementations

impl JSONParser

pub fn new() -> JSONParser

Available on crate feature parsers only.

Create a new JSONParser with default settings (strict mode, empty not allowed).

Examples

use reinhardt_core::parsers::json::JSONParser;

let parser = JSONParser::new();
assert!(!parser.allow_empty);
assert!(parser.strict);

pub fn allow_empty(self, allow: bool) -> JSONParser

Available on crate feature parsers only.

Examples

use reinhardt_core::parsers::json::JSONParser;

let parser = JSONParser::new().allow_empty(true);
assert!(parser.allow_empty);

pub fn strict(self, strict: bool) -> JSONParser

Available on crate feature parsers only.

Examples

use reinhardt_core::parsers::json::JSONParser;

let parser = JSONParser::new().strict(false);
assert!(!parser.strict);
