# Package sdml-errors

Rust Library containing the error and diagnostic types for the Simple Domain
Modeling Language (SDML).

[![Crates.io](https://img.shields.io/crates/v/sdml_errors.svg)](https://crates.io/crates/sdml_errors)
[![Docs.rs](https://img.shields.io/docsrs/sdml-errors.svg)](https://docs.rs/sdml_errors)

This package is part of the Rust SDML project and specifically defines the error
and diagnostic types for the project. The project's intent is to provide an
idiomatic implementation of the in-memory model, parser, generators, and the CLI
tool.

The following figure demonstrates this package in the broader project context.
