Re-imagining backend development in Rust

What is Pavex?

Pavex is a new framework to build APIs with Rust.

Pavex aims to have it all: great ergonomics and high performance.
The same productivity boost of Ruby on Rails, Spring or ASP.NET Core.
As fast as a handwritten solution that strips away all abstractions.

Check out Pavex's documentation for a thorough introduction to the framework and its design philosophy.

lib.rs:

This crate provides a custom graphical Miette handler for the Pavex project.

The handler is largely based on the miette::handlers::GraphicalHandler, with one key difference: we only report the code snippets from the related errors associated with a report. We have also done other minor tweaks to the graphical layout to better suit our needs.

This allows us to display snippets that come from different source files, a feature that doesn't have first-class support in miette. In other words, you can see this custom handler as a "hack" to avoid having to maintain a full fork of miette.
