Mutatability for values

Required methods

fn as_array_mut(&mut self) -> Option<&mut Self::Array>

Tries to represent the value as an array and returns a mutable refference to it

fn as_object_mut(&mut self) -> Option<&mut Self::Object>

Tries to represent the value as an object and returns a mutable refference to it

Provided methods

fn insert<K, V>(&mut self, k: K, v: V) -> Result<Option<Self>, AccessError> where
    K: Into<Self::Key>,
    V: Into<Self>,
    Self::Key: Hash + Eq, 

Tries to insert into this Value as an Object. Will return an AccessError::NotAnObject if called on a Value that isn't an object - otherwise will behave the same as HashMap::insert

Errors

Will return Err if self is not an object.

fn remove<Q: ?Sized>(&mut self, k: &Q) -> Result<Option<Self>, AccessError> where
    Self::Key: Borrow<Q> + Hash + Eq,
    Q: Hash + Eq + Ord, 

Tries to remove from this Value as an Object. Will return an AccessError::NotAnObject if called on a Value that isn't an object - otherwise will behave the same as HashMap::remove

Errors

Will return Err if self is not an Object.

fn push<V>(&mut self, v: V) -> Result<(), AccessError> where
    V: Into<Self>, 

Tries to push to this Value as an Array. Will return an AccessError::NotAnArray if called on a Value that isn't an Array - otherwise will behave the same as Vec::push

Errors

Will return Err if self is not an array.

fn pop(&mut self) -> Result<Option<Self>, AccessError>

Tries to pop from this Value as an Array. Will return an AccessError::NotAnArray if called on a Value that isn't an Array - otherwise will behave the same as Vec::pop

Errors

Will return Err if self is not an array.

fn get_mut<Q: ?Sized>(&mut self, k: &Q) -> Option<&mut Self> where
    Self::Key: Borrow<Q> + Hash + Eq,
    Q: Hash + Eq + Ord, 

Same as get but returns a mutable ref instead

fn get_idx_mut(&mut self, i: usize) -> Option<&mut Self>

Same as get_idx but returns a mutable ref instead
