Enum JsonValue 

pub enum JsonValue {
    Null,
    Bool(bool),
    Number(JsonNumber),
    String(String),
    Array(Vec<JsonValue>),
    Object(BTreeMap<String, JsonValue>),
}

Inspectable JSON that preserves number tokens and rejects duplicate keys.

Variants

Null

JSON null.

Bool(bool)

JSON boolean.

Number(JsonNumber)

Original, validated numeric token; no float conversion has occurred.

String(String)

Decoded Unicode text.

Array(Vec<JsonValue>)

Ordered array entries.

Object(BTreeMap<String, JsonValue>)

Unique object keys. Original ordering and escapes remain in reply bytes.

Implementations

impl JsonValue

pub fn parse(bytes: &[u8]) -> Result<Self, &'static str>

Decode exactly one JSON value, preserving unknown full-width numbers. Errors contain no payload excerpts or decoded values.

pub fn get(&self, name: &str) -> Option<&Self>

Look up one object field without converting its numeric values.

pub fn as_object(&self) -> Option<&BTreeMap<String, Self>>

Borrow object fields.

pub fn as_array(&self) -> Option<&[Self]>

Borrow ordered array entries.

pub fn as_str(&self) -> Option<&str>

Borrow decoded text.

pub fn as_bool(&self) -> Option<bool>

Read a boolean without coercion.

pub fn as_u64(&self) -> Option<u64>

Read a u64 integer token without a floating-point intermediate.

Trait Implementations

impl Clone for JsonValue

fn clone(&self) -> JsonValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JsonValue

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

Formats the value using the given formatter.

impl Drop for JsonValue

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Eq for JsonValue

impl PartialEq for JsonValue

fn eq(&self, other: &JsonValue) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
