Methods

impl Json
[src]

Decodes a json value from an &mut io::Read

Decodes a json value from a string

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.

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. Returns false otherwise.

If the Json value is an Object, returns a reference to the associated BTreeMap. Returns None otherwise.

If the Json value is an Object, returns a mutable reference to the associated BTreeMap. Returns None otherwise.

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

Returns true if the Json value is an Array. Returns false otherwise.

If the Json value is an Array, returns a reference to the associated vector. Returns None otherwise.

If the Json value is an Array, returns a mutable reference to the associated vector. Returns None otherwise.

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

Returns true if the Json value is a String. Returns false otherwise.

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

Returns true if the Json value is a Number. Returns false otherwise.

Returns true if the Json value is a i64. Returns false otherwise.

Returns true if the Json value is a u64. Returns false otherwise.

Returns true if the Json value is a f64. Returns false otherwise.

If the Json value is a number, return or cast it to a i64. Returns None otherwise.

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

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

Returns true if the Json value is a Boolean. Returns false otherwise.

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

Returns true if the Json value is a Null. Returns false otherwise.

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