Struct AddableDict 

pub struct AddableDict(pub HashMap<String, Value>);

Dictionary that can be added to another dictionary.

When adding two AddableDict instances:

• Keys only in the other dict are added
• Keys with null values in self are replaced
• Values that support addition are added together
• Otherwise the value from other replaces the value in self

Tuple Fields

0: HashMap<String, Value>

Implementations

impl AddableDict

pub fn new() -> Self
