Implementations

Borrow this json object as a pretty object to generate a pretty representation for it via Display.

If the Json value is an Object, returns the value associated with the provided key. Otherwise, returns None.

If the Json value is an Object, deletes the value associated with the provided key from the Object and returns it. Otherwise, returns None.

Attempts to get a nested Json Object for each key in keys. If any key is found not to exist, find_path will return None. Otherwise, it will return the Json value associated with the final key.

If the Json value is an Object, performs a depth-first search until a value associated with the provided key is found. If no value is found or the Json value is not an Object, returns None.

Returns true if the Json value is an Object.

If the Json value is an Object, returns the associated BTreeMap; returns None otherwise.

Returns true if the Json value is an Array.

If the Json value is an Array, returns the associated vector; returns None otherwise.

Returns true if the Json value is a String.

If the Json value is a String, returns the associated str; returns None otherwise.

Returns true if the Json value is a Number.

Returns true if the Json value is an i64.

Returns true if the Json value is a u64.

Returns true if the Json value is a f64.

If the Json value is a number, returns or cast it to an i64; returns None otherwise.

If the Json value is a number, returns or cast it to a u64; returns None otherwise.

If the Json value is a number, returns or cast it to a f64; returns None otherwise.

Returns true if the Json value is a Boolean.

If the Json value is a Boolean, returns the associated bool; returns None otherwise.

Returns true if the Json value is a Null.

If the Json value is a Null, returns (); returns None otherwise.
