[−][src]Struct col_macros::DropBy

pub struct DropBy<T, F> where
    F: FnMut(&mut T),  {
    pub value: T,
    pub clos: F,
}

A wrapper that calls the given closure at Drop. Useful when you have a conditional assign of one that,once assigned,you want to warranty a call to it with the given T,and then drop it.

It derefs to T.

Fields
