Macro object

macro_rules! object {
    {} => { ... };
    {
        $( $key: ident $(: $value: expr)? ),* $(,)?
    } => { ... };
    (@entry $hm: expr,
        $key: ident
    ) => { ... };
    (@entry $hm: expr,
        $key: ident : $value: expr
    ) => { ... };
}

Create a json-like ‘object’: A map of string keys to json values

unreact::Object is a type alias for serde_json::Map<String, serde_json::Value>

Similar to serde_json::json! macro, but must be an object

Examples

let my_key = "Hello!";
object! {
    foo: 123,
    bar: vec![4, 5, 6],
    // Use variable with same name as key
    my_key,
    // Nested objects must also use `object!` macro
    nested: object! {
        key: "value"
    }
};

The above code is equivalent to this json:

{
    "foo": 123,
    "bar": [4, 5, 6],
    "my_key": "Hello!",
    "nested": {
        "key": "value"
    }
}
