Arista Go library 
areflect
Helper functions to work with the reflect package. Contains
ForceExport(), which bypasses the check in reflect.Value that
prevents accessing unexported attributes.
monotime
Provides access to a fast monotonic clock source, to fill in the gap in the
Go standard library, which lacks one.
Don't use time.Now() in code that needs to time things or otherwise assume
that time passes at a constant rate, instead use monotime.Now().
cmd
See the cmd directory.
dscp
Provides ListenTCPWithTOS(), which is a replacement for net.ListenTCP()
that allows specifying the ToS (Type of Service), to specify DSCP / ECN /
class of service flags to use for incoming connections.
key
Provides a common type used across various Arista projects, named key.Key,
which is used to work around the fact that Go can't let one
use a non-hashable type as a key to a map, and we sometimes need to use
a map[string]interface{} (or something containing one) as a key to maps.
As a result, we frequently use map[key.Key]interface{} instead of just
map[interface{}]interface{} when we need a generic key-value collection.
lanz
A client for LANZ streaming servers. It connects to a LANZ streaming server, listens for notifications, decodes them and sends the LANZ protobuf on the provided channel.
monitor
A library to help expose monitoring metrics on top of the
expvar infrastructure.
netns
netns.Do(namespace, cb) provides a handy mechanism to execute the given
callback cb in the given network namespace.
pathmap
A datastructure for mapping keys of type string slice to values. It allows for some fuzzy matching.
test
This is a Go library to help in writing unit tests.
