## What it is
Strum is a small Rust library providing macros and traits for working with enums and strings. It offers custom derives like EnumString, Display, EnumIter, and EnumMessage to convert between enums and strings, iterate variants, and attach metadata.

## Use cases
- convert strings to enum variants in rust
- convert enum variants to strings
- iterate over all variants of a rust enum
- add custom properties or messages to enum variants
- convert integers to enums via discriminant
- count the number of enum variants

## When to choose
- you need string parsing or formatting for rust enums
- you want to iterate or enumerate enum variants
- you need static string representations of enum variants

## When to avoid
- your project must support rustc older than 1.71.1
- you need serialization to structured formats like JSON or YAML rather than strings

## Facets
- artifact type: library
- maturity: stable
- function: serialization, developer-tools
- domain: developer-tools, programming-languages
- platform: rust, cross-platform
- tags: enums, proc-macros, derive-macros, string-conversion, rust-library
