pub trait ExplicitDrop {
type ExplicitDropParam;
type ExplicitDropResult;
// Required method
fn explicit_drop(
self,
param: &Self::ExplicitDropParam,
) -> Self::ExplicitDropResult;
}Expand description
Trait for a type that provides an explicit method for dropping its value.
Unlike the Drop trait, this traits method:
- Can take a parameter
- Can return something
- Consumes the value (instead of taking a
&mut)
Unfortunately there is no built-in way to ensure a type is explicitly
dropped. One workaround is for a type to also implement Drop, and have
that implementation validate that ExplicitDrop::explicit_drop was called.
