[−][src]Trait arithmetic_eval::ModuleId
Identifier of an ExecutableModule. This is usually a "small" type,
such as an integer or a string.
The ID is provided when creating a module. It is displayed
in error messages (using Display::fmt). ModuleId is also associated with some types
(e.g., InterpretedFn and CodeInModule), which allows to obtain module info.
This can be particularly useful for outputting rich error information.
A ModuleId can be downcast to a specific type, similarly to Any.

Implementations
impl dyn ModuleId[src]
pub fn is<T: ModuleId>(&self) -> bool[src]
Returns true if the boxed type is the same as T.
This method is effectively a carbon copy of <dyn Any>::is. Such a copy is necessary
because &dyn ModuleId cannot be converted to &dyn Any, despite ModuleId having Any
as a super-trait.
pub fn downcast_ref<T: ModuleId>(&self) -> Option<&T>[src]
Returns a reference to the boxed value if it is of type T, or None if it isn't.
This method is effectively a carbon copy of <dyn Any>::downcast_ref. Such a copy
is necessary because &dyn ModuleId cannot be converted to &dyn Any, despite ModuleId
having Any as a super-trait.
