Enum JsonData 

pub enum JsonData {
    Null,
    Bool(bool),
    Integer(i64),
    Float(f64),
    String(String),
    Array(Vec<JsonData>),
    Object(HashMap<String, JsonData>),
}

Domain-specific representation of JSON-like data This replaces serde_json::Value to maintain Clean Architecture principles

Variants

Null

Null value

Bool(bool)

Boolean value

Integer(i64)

Integer value

Float(f64)

Float value (stored as f64 for simplicity)

String(String)

String value

Array(Vec<JsonData>)

Array of JsonData values

Object(HashMap<String, JsonData>)

Object with string keys and JsonData values

Implementations

impl JsonData

pub fn null() -> JsonData

Create a new null value

pub fn bool(value: bool) -> JsonData

Create a new boolean value

pub fn integer(value: i64) -> JsonData

Create a new integer value

pub fn float(value: f64) -> Result<JsonData, DomainError>

Create a new float value.

Returns Err when value is NaN or infinite. JSON (RFC 8259 §6) does not allow non-finite numbers, so a JsonData containing one could never be serialized to valid JSON.

Examples

use pjson_rs_domain::value_objects::JsonData;

assert!(JsonData::float(3.14).is_ok());
assert!(JsonData::float(f64::NAN).is_err());
assert!(JsonData::float(f64::INFINITY).is_err());
