Struct obstack::Ref

pub struct Ref<'a, T: 'a + ?Sized> { /* fields omitted */ }

A wrapper referencing a value in an Obstack.

A Ref value is owns the value it references, and will invoke drop on the value when the Ref goes out of scope. Effectively a Ref is a Box that uses an Obstack rather than the heap.

Trait Implementations
