leo-errors
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- Meaning outdated errors will just deprecated.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
The common section of this crate contains a few sub files:
- Backtraced Error: Which contains the information needed to create a backtraceable error for Leo.
- Formatted Error: Which contains the information needed to create a formatted error for Leo.
- Macros: Which contains the logic to make creating errors easy through a DSL. It also figures out the error codes for each error via a top down method. Meaning all new errors should be added to the bottom of the file. You can specify whether an error is formatted or backtraced through a decorator above a function name, where the formatted ones require a Span as an argument by default. The body takes any additional arguments you want provided to the function, the message, and the optional help message for the error. The additional arguments are just specified to implement traits to avoid as many type conversions in other Leo crates.
- Span: Which contains the span object used throughout the other Leo crates (with the exception of the Input crate see more below).
- Traits: Which contains the common traits in errors to make defining errors easier.
Error Types
These are the different kinds of errors that are made in this crate. Note that if you want more information about the errors please check the crates documentation or the Error Index. All errors here with the exception of SnarkVM Errors have a 037 prefixed to their error codes.
ASG
The errors for the leo-asg crate. Its error codes will range from 3_000-3_999 and be prefixed with the characters ASG.
AST
The errors for the leo-ast crate. Its error codes will range from 2_000-2_999 and be prefixed with the characters AST.
CLI
The errors for the leo-lang crate. Its error codes will range from 7_000-7_999 and be prefixed with the characters CLI.
Compiler
The errors for the leo-compiler crate. Its error codes will range from 6_000-6_999 and be prefixed with the characters CMP.
Import
The errors for the leo-imports crate. Its error codes will range from 4_000-4_999 and be prefixed with the characters IMP.
Input
The errors for the leo-ast crate. Its error codes will range from 8_000-8_999 and be prefixed with the characters INP.
Package
The errors for the leo-package crate. Its error codes will range from 5_000-5_999 and be prefixed with the characters PAK.
Parser
The errors for the leo-parser crate. Its error codes will range from 0-999 and be prefixed with the characters PAR.
SnarkVM
The errors from SnarkVM that bubble up into Leo in some situations. For right now, they have an exit code of 1. When SnarkVM implements better error codes and messages, we can bubble them up.
State
The errors for the leo-state crate. Its error codes will range from 1_000-1_999 and be prefixed with the characters STA.
