base on Transports, Middleware, and Networks for the Alloy project # Alloy Alloy connects applications to blockchains. Alloy is a rewrite of [`ethers-rs`] from the ground up, with exciting new features, high performance, and excellent [docs](https://docs.rs/alloy). We also have a [book](https://alloy.rs/) on all things Alloy and many [examples](https://github.com/alloy-rs/examples) to help you get started.

The easiest way to get started is to add the `alloy` crate with the `full` feature flag from the command-line using Cargo: ```sh cargo add alloy --features full ``` Alternatively, you can add the following to your `Cargo.toml` file: ```toml alloy = { version = "0.3", features = ["full"] } ``` For a more fine-grained control over the features you wish to include, you can add the individual crates to your `Cargo.toml` file, or use the `alloy` crate with the features you need. A comprehensive list of available features can be found on [docs.rs](https://docs.rs/crate/alloy/latest/features) or in the [`alloy` crate's `Cargo.toml`](https://github.com/alloy-rs/alloy/blob/main/crates/alloy/Cargo.toml). ## Overview This repository contains the following crates: -

clippy.toml - Cargo.toml - .github/workflows/ci.yml --> The current MSRV (minimum supported rust version) is 1.81. Alloy will keep a rolling MSRV policy of **at least** two versions behind the latest stable release (so if the latest stable release is 1.58, we would support 1.56). Note that the MSRV is not increased automatically, and only as part of a patch (pre-1.0) or minor (post-1.0) release. ## Contributing Thanks for your help improving the project! We are so happy to have you! We have [a contributing guide](./CONTRIBUTING.md) to help you get involved in the Alloy project. Pull requests will not be merged unless CI passes, so please ensure that your contribution follows the linting rules and passes clippy. ## Note on `no_std` Because these crates are primarily network-focused, we do not intend to support `no_std` for most of them at this time. The following crates support `no_std`: - alloy-eips - alloy-genesis - alloy-serde - alloy-consensus If you would like to add `no_std` support to a crate, please make sure to update `scripts/check_no_std.sh` as well. ## Credits None of these crates would have been possible without the great work done in: - [`ethers.js`](https://github.com/ethers-io/ethers.js/) - [`rust-web3`](https://github.com/tomusdrw/rust-web3/) - [`ruint`](https://github.com/recmo/uint) - [`ethabi`](https://github.com/rust-ethereum/ethabi) - [`ethcontract-rs`](https://github.com/gnosis/ethcontract-rs/) - [`guac_rs`](https://github.com/althea-net/guac_rs/) #### License ^{Licensed under either of <a href="LICENSE-APACHE">Apache License, Version 2.0</a> or <a href="LICENSE-MIT">MIT license</a> at your option.} <br> _{Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in these crates by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions.} ", Assign "at most 3 tags" to the expected json: {"id":"6869","tags":[]} "only from the tags list I provide: [{"id":77,"name":"3d"},{"id":89,"name":"agent"},{"id":17,"name":"ai"},{"id":54,"name":"algorithm"},{"id":24,"name":"api"},{"id":44,"name":"authentication"},{"id":3,"name":"aws"},{"id":27,"name":"backend"},{"id":60,"name":"benchmark"},{"id":72,"name":"best-practices"},{"id":39,"name":"bitcoin"},{"id":37,"name":"blockchain"},{"id":1,"name":"blog"},{"id":45,"name":"bundler"},{"id":58,"name":"cache"},{"id":21,"name":"chat"},{"id":49,"name":"cicd"},{"id":4,"name":"cli"},{"id":64,"name":"cloud-native"},{"id":48,"name":"cms"},{"id":61,"name":"compiler"},{"id":68,"name":"containerization"},{"id":92,"name":"crm"},{"id":34,"name":"data"},{"id":47,"name":"database"},{"id":8,"name":"declarative-gui "},{"id":9,"name":"deploy-tool"},{"id":53,"name":"desktop-app"},{"id":6,"name":"dev-exp-lib"},{"id":59,"name":"dev-tool"},{"id":13,"name":"ecommerce"},{"id":26,"name":"editor"},{"id":66,"name":"emulator"},{"id":62,"name":"filesystem"},{"id":80,"name":"finance"},{"id":15,"name":"firmware"},{"id":73,"name":"for-fun"},{"id":2,"name":"framework"},{"id":11,"name":"frontend"},{"id":22,"name":"game"},{"id":81,"name":"game-engine "},{"id":23,"name":"graphql"},{"id":84,"name":"gui"},{"id":91,"name":"http"},{"id":5,"name":"http-client"},{"id":51,"name":"iac"},{"id":30,"name":"ide"},{"id":78,"name":"iot"},{"id":40,"name":"json"},{"id":83,"name":"julian"},{"id":38,"name":"k8s"},{"id":31,"name":"language"},{"id":10,"name":"learning-resource"},{"id":33,"name":"lib"},{"id":41,"name":"linter"},{"id":28,"name":"lms"},{"id":16,"name":"logging"},{"id":76,"name":"low-code"},{"id":90,"name":"message-queue"},{"id":42,"name":"mobile-app"},{"id":18,"name":"monitoring"},{"id":36,"name":"networking"},{"id":7,"name":"node-version"},{"id":55,"name":"nosql"},{"id":57,"name":"observability"},{"id":46,"name":"orm"},{"id":52,"name":"os"},{"id":14,"name":"parser"},{"id":74,"name":"react"},{"id":82,"name":"real-time"},{"id":56,"name":"robot"},{"id":65,"name":"runtime"},{"id":32,"name":"sdk"},{"id":71,"name":"search"},{"id":63,"name":"secrets"},{"id":25,"name":"security"},{"id":85,"name":"server"},{"id":86,"name":"serverless"},{"id":70,"name":"storage"},{"id":75,"name":"system-design"},{"id":79,"name":"terminal"},{"id":29,"name":"testing"},{"id":12,"name":"ui"},{"id":50,"name":"ux"},{"id":88,"name":"video"},{"id":20,"name":"web-app"},{"id":35,"name":"web-server"},{"id":43,"name":"webassembly"},{"id":69,"name":"workflow"},{"id":87,"name":"yaml"}]" returns me the "expected json"
