## What it is
quick-xml is a high-performance XML pull reader and writer library for Rust, featuring near zero-copy parsing with Cow types and buffer reuse. It supports multiple encodings, namespace resolution, entity unescaping, and optional serde-based serialization/deserialization.

## Use cases
- parse large xml files fast in rust
- read xml config files with low memory allocation
- write xml documents programmatically
- deserialize xml into rust structs with serde
- parse html-like markup
- stream-process xml events without loading whole document

## When to choose
- you need maximum xml parsing performance in Rust
- you want zero-copy or low-allocation parsing
- you need serde integration for xml
- you need encoding or namespace support

## When to avoid
- you need DOM-style tree access rather than pull events
- you need full XML schema validation
- you are not working in Rust

## Facets
- artifact type: library
- maturity: stable
- function: parser, serialization, web-scraping
- domain: parsers, web-development, developer-tools
- platform: rust, cross-platform
- tags: xml, pull-parser, zero-copy, serde-support, html-parsing
