## What it is
go-querystring is a small Go library that encodes structs into URL query parameters via struct tags. It exposes a single Values() function and is widely used, notably by go-github.

## Use cases
- build url query strings from a struct in go
- type-safe query parameters for api requests
- encode struct fields with url tags
- construct paginated api request urls
- convert go struct to url.values

## When to choose
- you need to encode structs into query strings in Go with type safety
- you want a tiny, stable, widely-adopted library
- you already use struct tags like encoding/json and want similar ergonomics

## When to avoid
- you need to decode query strings back into structs
- you need complex nested or custom serialization beyond query parameters

## Facets
- artifact type: library
- maturity: stable
- function: serialization, http-client
- domain: web-development, developer-tools
- platform: go
- tags: query-string, struct-tags, url-encoding
