| bufio | Package bufio implements buffered I/O. It wraps an io.Reader or io.Writer object, creating another object (Reader or Writer) that also implements the interface but provides buffering and some help for textual I/O. |
| bytes | Package bytes implements functions for the manipulation of byte slices. |
| fmt | Package fmt implements formatted I/O with functions analogous to C's printf and scanf. |
| github.com/prometheus/client_model/go | |
| github.com/prometheus/common/model | Package model contains common data structures that are shared across Prometheus components and libraries. |
| io | Package io provides basic interfaces to I/O primitives. |
| math | Package math provides basic constants and mathematical functions. |
| path | Package path implements utility routines for manipulating slash-separated paths. |
| regexp | Package regexp implements regular expression search. |
| runtime/metrics | Package metrics provides a stable interface to access implementation-defined metrics exported by the Go runtime. |
| sort | Package sort provides primitives for sorting slices and user-defined collections. |
| strings | Package strings implements simple functions to manipulate UTF-8 encoded strings. |
