Required Methods§

Source

fn as_object(&self) -> Option<&Self::ObjectType>

Returns the object if self is an object.

§Examples

use sonic_rs::{json, object, JsonContainerTrait, JsonValueTrait, Value};

let value: Value = sonic_rs::from_str(r#"{"a": 1, "b": true}"#).unwrap();

assert!(value.is_object());
assert_eq!(value.as_object(), Some(&object! {"a": 1, "b": true}));

Source

fn as_array(&self) -> Option<&Self::ArrayType>

Returns the array if self is an array.

§Examples

use sonic_rs::{array, json, JsonContainerTrait, JsonValueTrait, Value};

let value: Value = sonic_rs::from_str(r#"[1, 2, 3]"#).unwrap();

assert!(value.is_array());
assert_eq!(value.as_array(), Some(&array![1, 2, 3]));
