...Envconfig won't process a field with the "ignored" tag set to "true", even if a corresponding environment variable is set. Any field whose type (or pointer-to-type) implements envconfig.Decoder can control its own deserialization. Also, envconfig will use a Set(string) error method like from the flag.Value interface if implemented.

...Structs containPackage structs contains various utilities functions to work with structs various utilities to work with Go (Golang) structs. It was initially used by me to convert a struct into a map[string]interface{}. With time I've added other utilities for structs.

Globally Unique ID Generator is a Go library for generating globally unique identifiers that are compact, sortable, and safe to use directly in server-side code. It uses a MongoDB ObjectID-inspired structure with a timestamp, machine identifier, process identifier, and counter. The binary form is 12 bytes, while the string form uses lowercase base32hex encoding to create a 20-character URL-safe representation. This makes xid shorter than standard UUID strings while preserving chronological sortability. It does not require a central generator server or explicit machine and data-center configuration, which makes it convenient for distributed web services. ...

go-cache is an in-memory key:value store/cache similar to memcached that is suitable for applications running on a single machine. Its major advantage is that, being essentially a thread-safe map[string]interface{} with expiration times, it doesn't need to serialize or transmit its contents over the network. Any object can be stored, for a given duration or forever, and the cache can be safely used by multiple goroutines. Although go-cache isn't meant to be used as a persistent datastore, the entire cache can be saved to and loaded from a file (using c.Items() to retrieve the items map to serialize, and NewFrom() to create a cache from a deserialized one) to recover from downtime quickly.

Sometimes, you can't know ahead-of-time what an expression will look like, or you want those expressions to be configurable. Perhaps you've got a set of data running through your application, and you want to allow your users to specify some validations to run on it before committing it to a database. Or maybe you've written a monitoring framework which is capable of gathering a bunch of metrics, then evaluating a few expressions to see if any metrics should be alerted upon, but the...
