Implementations

impl<T: Json> Value<T>

pub fn is_null(&self) -> bool

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

Returns true if the value is a number. Returns false otherwise.

For any value on which is_number returns true, as_number is guaranteed to return the number value.

Returns true if the value is a string. Returns false otherwise.

For any value on which is_string returns true, as_str is guaranteed to return the string value.

pub fn is_array(&self) -> bool

Returns true if the value is an array. Returns false otherwise.

For any value on which is_array returns true, as_array is guaranteed to return the array value.

pub fn is_object(&self) -> bool

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

pub fn as_number(&self) -> Option<&T::Number>
