/// The main type of rule run by the runner. The rule takes individual
/// nodes inside of a Concrete Syntax Tree and checks them.
/// It may also take individual syntax tokens.
/// Rule must be all be [`Send`] + [`Sync`], because rules are run in parallel.
///
/// # Rule Level Configuration
/// Rules do not know about the lint level they were configured for, the runner
/// runs the rules, then maps any error/warning diagnostics to their appropriate severity.
/// This saves on boilerplate code for getting the appropriate diagnostic builder type and config.
///
/// # Guidelines
/// This is a list of guidelines and tips you should generally follow when implementing a rule:
/// - Do not use text based equality, it is inaccurate, instead use [`lexical_eq`](SyntaxNodeExt::lexical_eq).
/// - Avoid using `text_range` on nodes, it is inaccurate because it may include whitespace, instead use [`trimmed_range`](SyntaxNodeExt::trimmed_range).
/// - Avoid using `text` on nodes for the same reason as the previous, use [`trimmed_text`](SyntaxNodeExt::trimmed_text).
/// - If you can offer better diagnostics and more context around a rule error, __always__ do it! It is a central goal
/// of the project to offer very helpful diagnostics.
/// - Do not be afraid to clone syntax nodes, ast nodes, and syntax tokens. They are all backed by an [`Rc`](std::rc::Rc) around Node data.
/// therefore they can be cheaply cloned (but if you can, have your functions take a reference since Rc cloning is not zero cost).
/// - Do not try to rely on the result of other rules, it is impossible because rules are run at the same time.
/// - Do not rely on file data of different files. There is a separate rule type for this.
/// - Do not unwrap pieces of an AST node (sometimes it is ok because they are guaranteed to be there), since that will cause panics
/// with error recovery.
/// - Do not use node or string coloring outside of diagnostic notes, it messes with termcolor and ends up looking horrible.

//! <p>Amazon Managed Blockchain is a fully managed service for creating and managing blockchain networks using open-source frameworks. Blockchain allows you to build applications where multiple parties can securely and transparently run transactions and share data without the need for a trusted, central authority.</p>
//! <p>Managed Blockchain supports the Hyperledger Fabric and Ethereum open-source frameworks. Because of fundamental differences between the frameworks, some API actions or data types may only apply in the context of one framework and not the other. For example, actions related to Hyperledger Fabric network members such as <code>CreateMember</code> and <code>DeleteMember</code> do not apply to Ethereum.</p>
//! <p>The description for each action indicates the framework or frameworks to which it applies. Data types and properties that apply only in the context of a particular framework are similarly indicated.</p>
//!
//! # Crate Organization
//!
//! The entry point for most customers will be [`Client`]. [`Client`] exposes one method for each API offered
//! by the service.
//!
//! Some APIs require complex or nested arguments. These exist in [`model`].
//!
//! Lastly, errors that can be returned by the service are contained within [`error`]. [`Error`] defines a meta
//! error encompassing all possible errors that can be returned by the service.
//!
//! The other modules within this crate and not required for normal usage.
//!
//! # Examples
// Code generated by software.amazon.smithy.rust.codegen.smithy-rs. DO NOT EDIT.

Dataset 1: TheStack - Rust - Cleaned
Description: This dataset is drawn from TheStack Corpus, an open-source code dataset with over 3TB of GitHub data covering 48 programming languages. We selected a small portion of this dataset to optimize smaller language models for Rust, a popular statically typed language.
Target Language: Rust
Dataset Size:
- Training: 900,000 files
- Validation: 50,000 files
- Test: 50,000 files
Preprocessing:
- Selected Rust as the target language due to its popularity on GitHub.
- Filtered out files with average line length > 100 characters, maximum line length > 1000 characters, and alphabet ratio < 25%.
- Split files into 90% training, 5% validation, and 5% test sets.
Tokenizer: Byte Pair Encoding (BPE) tokenizer with tab and whitespace tokens. GPT-2 vocabulary extended with special tokens.
Training Sequences: Sequences constructed by joining training data text to reach a context length of 2048 tokens (1024 tokens for full fine-tuning).
