## What it is
gimli is a Rust library for reading and writing the DWARF debugging format. It is zero-copy, lazy, and works with any object file format, usable even in no_std/embedded environments.

## Use cases
- parse DWARF debug info from binaries
- write DWARF debugging sections
- resolve addresses to source lines like addr2line
- build a dwarfdump-style debug info dumper
- convert or strip DWARF sections in a toolchain
- parse .debug_line line number programs

## When to choose
- you need fast, zero-copy DWARF parsing in Rust
- you're building debuggers, profilers, or symbolication tools
- you need no_std support for embedded tooling
- you want an object-file-format-agnostic DWARF reader/writer

## When to avoid
- you need a ready-made CLI like dwarfdump or addr2line rather than a library
- you need to parse object files themselves (use the object crate alongside)
- you work outside Rust and need bindings

## Facets
- artifact type: library
- maturity: stable
- function: parser, developer-tools, sdk
- domain: developer-tools, parsers, cross-platform
- platform: rust, cross-platform, embedded
- tags: dwarf, debug-info, zero-copy, elf, eh-frame, debugging-format, no-std
