## What it is
Tera is a template engine for Rust inspired by the Jinja2 and Django template languages. It lets developers define templates with inheritance, loops, filters, and custom functions, and render them with serde-based contexts.

## Use cases
- render HTML pages in a Rust web app
- generate emails from templates in Rust
- use Jinja2-style templates in a Rust project
- generate static site content from templates
- render configuration files or reports from data

## When to choose
- you are writing Rust and want familiar Jinja2/Django-style templating
- you need template inheritance, filters, and custom functions in Rust
- you want a lightweight, mature template engine with serde integration

## When to avoid
- you need exact Jinja2 compatibility or Python-specific features
- your project is not in Rust
- you need runtime user-editable templates with sandboxing guarantees

## Facets
- artifact type: library
- maturity: stable
- function: templating
- domain: web-development, developer-tools
- platform: rust, cross-platform
- tags: template-engine, jinja2, django, html, rust-library
