This directory contains the code for the Errors for all the Leo crates.
The errors are inspired by `rust` in a few different ways:
- Each error has its own unique code.
- Error codes will never be changed upon a stable release.
- Meaning outdated errors will just deprecated.
- In addition we had a unique identifier to let you know where the compiler found the error.
The purpose of these errors is such that searching an error in the documentation, or online for help, becomes easier.
## [Common](./src/common)
The common section of this crate contains a few sub files:
