Trait erupt::ExtendableFrom [−][src]
pub trait ExtendableFrom<'a, T> {
fn extend_from(self, addition: &'a mut T) -> Self
where
Self: Sized,
{ ... }
}Expand description
Provides type-safe pointer chain support.
Provided methods
fn extend_from(self, addition: &'a mut T) -> Self where
Self: Sized,
fn extend_from(self, addition: &'a mut T) -> Self where
Self: Sized,
Inserts addition (+ its pointer chain) between the head and tail of
this pointer chain.
- Head of
self- Head of
addition - Tail of
addition - Tail of
addition - Tail of
addition - …
- Head of
- Tail of
self - Tail of
self - Tail of
self - …
The implementation is like this specifically, because this trait is only
ever implemented on the “main carrier” of the pointer chain, which means
that addition doesn’t usually have a “tail” (unless, you’ve set the
pointers by yourself, which this consequently also supports). This saves
us from iterating the entire pointer chain each time an item is added.
