Methods

impl Json
[src]

[src]

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

[src]

Decodes a json value from a string

[src]

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

[src]

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

[src]

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.

[src]

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.

[src]

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

[src]

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

[src]

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

[src]

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

[src]

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

[src]

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

[src]

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

[src]

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

[src]

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

[src]

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

[src]

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

[src]

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

[src]

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

[src]

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

[src]

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

[src]

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

[src]

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

[src]

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

[src]

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

[src]

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

[src]

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