基类：EventHandling, Generic[VarType]

Aimed to provide experience like C vars with pointers.

Args:

default_value: The initial _value of the variable. value_type: The type of the variable.

__init__(default_value: VarType | None = None)

property value: VarType | None

The value stored in the var.

charmy.utils.var.unpack_var(var_or_val: Var[VarType] | VarType, default: None = None) → VarType | None

charmy.utils.var.unpack_var(var_or_val: Var[VarType] | VarType, default: VarType) → VarType

To convert a var to its value if param 1 is a var, otherwise return the param 1 as-is.

参数:
