# Directory Structure¶

We follow the best practice structure here which is also made by cargo.

The structure can be a workspace with multiple packages (in sub directories) or a single package.

## Cargo.toml / Cargo.lock¶

This contains some metadata and is stored in the root of the workspace and package. The Manifest Format

## src¶

The main directory for all sources of the library or binary in the package.

• main.rs - the start point of a binary
• lib.rs - the start point of a library

Modules with submodules will have sub directories. Here the mod.rs contains the parent module and the child modules are there as separate files or directories with their files.

## tests¶

Containing integration tests of each package.

## targets¶

Everything created while building, debugging and testing will be made here. It is also the folder you find your created binaries only in the top level workspace or package.
