# Vel



A language for verified low-level software.

It dreams to be something like *Rust with logic*  

― a language that empowers people to build verified low-level software.

## Name

The name Vel stands for various concepts.

Vel is a language for *ve*rified *l*ow-level software.

Vel commits to the *vel*ocity of both development and runtime.

Vel wants to be smooth and relaxing like *vel*vet.

## Type system

Vel features a dependent ownership type system.

It enables reasoning about runtime objects using some propositions.  

Some propositions are copyable (like Rust's `Copy`), but others are not ― as we are in separation logic!

We can also use Rust-like borrows for sharing, very unlike traditional separation logic.

## Architecture

- [`vel`](./vel): Vel's language engine, written in Rust.

- [`vel-vscode`](./vel-vscode): VS Code extension for Vel.
