Percpu is a Go package to support best-effort CPU-local sharded values.
This package is something of an experiment. See Go issue #18802 for discussion about adding this functionality into the Go standard library.
This version is updated to use generics.
- This package uses
go:linknameto access unexported functions from inside the Go runtime. Those could be changed or removed in a future Go version, breaking this package. - It may be tempting to use this package to solve problems for which there are better solutions that do not break key abstractions of the runtime.
See When to use percpu for a discussion about when this package may or may not be appropriate.
