Enum rustc_target::json::Json

pub enum Json {
    Null,
    Bool(bool),
    Number(Number),
    String(String),
    Array(Vec<Value, Global>),
    Object(Map<String, Value>),
}

Represents any valid JSON value.

See the serde_json::value module documentation for usage examples.

Variants

Null

Represents a JSON null value.

let v = json!(null);

Bool(bool)

Represents a JSON boolean.

let v = json!(true);

Number(Number)

Represents a JSON number, whether integer or floating point.

let v = json!(12.5);

String(String)

Represents a JSON string.

let v = json!("a string");

Array(Vec<Value, Global>)

Represents a JSON array.

let v = json!(["an", "array"]);

Object(Map<String, Value>)

Represents a JSON object.

By default the map is backed by a BTreeMap. Enable the preserve_order feature of serde_json to use IndexMap instead, which preserves entries in the order they are inserted into the map. In particular, this allows JSON data to be deserialized into a Value and serialized to a string while retaining the order of map keys in the input.

let v = json!({ "an": "object" });

Trait Implementations

impl<'a> PartialEq<Value> for &'a str

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialEq<Value> for str

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl ToJson for Json

fn to_json(&self) -> Json

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
