Implementations

impl<'a, T: Json> ValueRef<'a, T>

pub fn is_null(&self) -> bool

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

pub fn is_bool(&self) -> bool

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

For any value on which is_boolean returns true, as_bool is guaranteed to return the boolean value.

pub fn is_number(&self) -> bool

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.

pub fn is_string(&self) -> bool

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

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

For any value on which is_object returns true, as_object is guaranteed to return the object value.

impl<'a, T: Json> ValueRef<'a, T>

pub fn as_bool(&self) -> Option<bool>

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

pub fn as_number(&self) -> Option<&'a T::Number>

If the value is a number, returns a reference to it. Returns None otherwise.

pub fn as_str(&self) -> Option<&'a str>

If the value is a string, returns its associated str. Returns None otherwise.

pub fn as_array(&self) -> Option<&'a T::Array>

If the value is an array, returns a reference to it. Returns None otherwise.

pub fn as_object(&self) -> Option<&'a T::Object>

If the value is an object, returns a reference to it. Returns None otherwise.

pub fn cloned(&self) -> Value<T> where
    T::Number: Clone,
    T::String: From<&'a str>,
    T::Array: Clone,
    T::Object: Clone, 

Creates a new value by cloning the referenced value.
