Enum JsonValue 

pub enum JsonValue {
    String(String),
    Integer(i64),
    Float(f64),
    Boolean(bool),
    Null,
    Array(JsonArray),
    Object(JsonObject),
}

JSON value representation.

This represents the pure value of a JSON element without any source code location information.

Variants

String(String)

String value.

Integer(i64)

Integer value.

Float(f64)

Floating-point value.

Boolean(bool)

Boolean value.

Null

Null value.

Array(JsonArray)

Array value.

Object(JsonObject)

Object value.

Implementations

impl JsonValue

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

Returns the string slice if the value is a string.

pub fn as_integer(&self) -> Option<i64>

Returns the integer value if the value is an integer.

pub fn as_float(&self) -> Option<f64>

Returns the floating-point value if the value is a float.

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

Returns the boolean value if the value is a boolean.

pub fn is_null(&self) -> bool

Returns true if the value is null.

pub fn as_array(&self) -> Option<&Vec<JsonValue>>

Returns a reference to the array if the value is an array.

pub fn as_object(&self) -> Option<&HashMap<String, JsonValue>>

Returns a reference to the object if the value is an object.

pub fn get(&self, key: &str) -> Option<&JsonValue>

Gets a value from the object by key name.

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for JsonValue

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for JsonValue

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

Formats the value using the given formatter.

impl PartialEq for JsonValue

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
