Provided methods

fn has(&self, key: &str) -> Result<bool>

Checks a presence of the @p key in the dictionary.

unsafe fn ptr_mut(&mut self, key: &str) -> Result<DictValue>

If the @p key in the dictionary then returns pointer to its value, else returns NULL.

unsafe fn ptr(&self, key: &str) -> Result<DictValue>

fn get(&self, key: &str) -> Result<DictValue>

If the @p key in the dictionary then returns its value, else an error will be generated.

fn set(&mut self, key: &str, value: &mut DictValue) -> Result<DictValue>

Sets new @p value for the @p key, or adds new key-value pair into the dictionary.

fn erase(&mut self, key: &str) -> Result<()>

Erase @p key from the dictionary.
