Add a benchmark.

[TheVeryDarkness]

Added a benchmark, which parses automatically generated json data.

I think the performance is much worse than pest. Maybe test on pest later.

And I think we should add tests and benchmarks to CI.

Summary by CodeRabbit

• New Features
  • Introduced benchmarking for JSON parsing using pest3 and serde_json.
  • Added support for benchmarking deep and shallow JSON objects.

Walkthrough

The recent updates introduce benchmarking capabilities for JSON parsing within the derive directory. Dependencies for criterion and serde_json were added, and a new benchmark for JSON parsing was configured. Additionally, json.rs was created to define and benchmark parsing functions for both deep and shallow JSON objects using pest3 and serde_json.

Changes

File/Path	Change Summary
derive/Cargo.toml	Added dependencies: criterion and serde_json; Added benchmark configuration for JSON
derive/benches/json.rs	Introduced JsonParser struct and benchmarking functions for parsing JSON objects

Poem

In the realm of code so bright and keen,
Benchmarks now dance on the JSON scene.
With serde_json and criterion in play,
Parsing speeds are timed, come what may.
Deep or shallow, the objects we parse,
Our code now sings, a benchmarking star! 🌟

Tips

### Chat There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai): - Review comments: Directly reply to a review comment made by CodeRabbit. Example: - `I pushed a fix in commit .` - `Generate unit testing code for this file.` - `Open a follow-up GitHub issue for this discussion.` - Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples: - `@coderabbitai generate unit testing code for this file.` - `@coderabbitai modularize this function.` - PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples: - `@coderabbitai generate interesting stats about this repository and render them as a table.` - `@coderabbitai show all the console.log statements in this repository.` - `@coderabbitai read src/utils.ts and generate unit testing code.` - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.` - `@coderabbitai help me debug CodeRabbit configuration file.` Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments. ### CodeRabbit Commands (invoked as PR comments) - `@coderabbitai pause` to pause the reviews on a PR. - `@coderabbitai resume` to resume the paused reviews. - `@coderabbitai review` to trigger an incremental review. This is useful when automatic reviews are disabled for the repository. - `@coderabbitai full review` to do a full review from scratch and review all the files again. - `@coderabbitai summary` to regenerate the summary of the PR. - `@coderabbitai resolve` resolve all the CodeRabbit review comments. - `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository. - `@coderabbitai help` to get help. Additionally, you can add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. ### CodeRabbit Configration File (`.coderabbit.yaml`) - You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository. - Please see the [configuration documentation](https://docs.coderabbit.ai/guides/configure-coderabbit) for more information. - If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: `# yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json` ### Documentation and Community - Visit our [Documentation](https://coderabbit.ai/docs) for detailed information on how to use CodeRabbit. - Join our [Discord Community](https://discord.com/invite/GsXnASn26c) to get help, request features, and share feedback. - Follow us on [X/Twitter](https://twitter.com/coderabbitai) for updates and announcements.

And we can add some features to improve typed api's performance, such as using an allocator/arena and adding a rule optimizer (but it's harder on typed api, and in some cases it can only work as a linter). I may have some time after around a month. @tomtau Do you have any plan on our future works?

Thanks a lot @TheVeryDarkness !

@tomtau Do you have any plan on our future works?

I opened a few issues for near-term priorities: https://github.com/pest-parser/pest3/issues feel free to comment on any that you'd be interested in tackling
