Struct immutable_arena::Arena
[−]
[src]
pub struct Arena<T> { // some fields omitted }
An Arena<T>
is a container of objects of type T
that, once allocated,
live as long as the containing arena. Within the arena, objects may refer
to other objects using the Ref<'arena, T>
smart-pointer type. These
object references are allowed to form cycles. Once created, an object is
immutable. However, any Ref<'arena, T>
instances within the object may be
set exactly once. The common usage pattern is to create objects and set
all their refs before returning them to user code; the objects are
subsequently completely immutable.
