pub struct Ptr<'b, T: 'b>(pub &'b T);
Expand description
A reference that is hashed and compared by its pointer value.
Ptr
is used for certain configurations of GraphMap
,
in particular in the combination where the node type for
GraphMap
is something of type for example Ptr(&Cell<T>)
,
with the Cell<T>
being TypedArena
allocated.
