### New weak package
|
|
|
|
The new [weak](/pkg/weak) package provides weak pointers.
|
|
|
|
Weak pointers are a low-level primitive provided to enable the
|
|
creation of memory-efficient structures, such as weak maps for
|
|
associating values, canonicalization maps for anything not
|
|
covered by package [unique](/pkg/unique), and various kinds
|
|
of caches.
|
|
For supporting these use-cases, this release also provides
|
|
[runtime.AddCleanup](/pkg/runtime#AddCleanup) and
|
|
[maphash.Comparable](/pkg/maphash#Comparable).
