Expand description

Mutatability for values

Required methods

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

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>[src]

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::Target>, AccessError> where
    K: Into<Self::Key>,
    V: Into<Self::Target>,
    Self::Key: Hash + Eq, [src]

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 try_insert<K, V>(&mut self, k: K, v: V) -> Option<Self::Target> where
    K: Into<Self::Key>,
    V: Into<Self::Target>,
    Self::Key: Hash + Eq, [src]

Tries to insert into this Value as an Object. If the Value isn’t an object this opoeration will return None and have no effect.

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

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 try_remove<Q: ?Sized>(&mut self, k: &Q) -> Option<Self::Target> where
    Self::Key: Borrow<Q> + Hash + Eq,
    Q: Hash + Eq + Ord, [src]

Tries to remove from this Value as an Object. If the Value isn’t an object this opoeration will return None and have no effect.

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

Pushes 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 try_push<V>(&mut self, v: V) where
    V: Into<Self::Target>, [src]

Tries to push to a Value if as an Array. This funciton will have no effect if Value is of a different type

fn pop(&mut self) -> Result<Option<Self::Target>, AccessError>[src]

Pops 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 try_pop(&mut self) -> Option<Self::Target>[src]

Tries to pop from a Value as an Array. if the Value is any other type None will always be returned

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

Same as get but returns a mutable ref instead

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

Same as get_idx but returns a mutable ref instead
