Rust Parser

Open-source Rust projects categorized as Parser

Top 23 Rust Parser Projects

  • GitHub repo vector

    A high-performance, high-reliability observability data pipeline.

    Project mention: AWS releases forked Elasticsearch code. Announces new name: OpenSearc | | 2021-04-12
  • GitHub repo nom

    Rust parser combinator framework

    Project mention: How can I make this code more "rusty" | | 2021-04-12

    I second /u/ejaszewski's recommendations, and would add: if you are going to be expanding this code, and adding more token types, there are parser/tokenizer crates such as nom that would be worth investigation. If not, hand-crafted code like this is fine. Nom is great, but overkill for such a simple job.

  • GitHub repo pest

    The Elegant Parser

    Project mention: Rust's Type System Is Turing-Complete | | 2021-03-15

    I used the pest[1] library in Rust, it uses something a bit like an EBNF syntax to write the grammar and generate a PEG parser.

  • GitHub repo lalrpop

    LR(1) parser generator for Rust

    Project mention: Ditch regex for parser combinators, a Rust / nom step-by-step guide | | 2021-03-30

    Do you mean for C++ in particular, or just for any language? Because LALRPOP is very good if you're not specifically looking for C++.

  • GitHub repo rslint

    A (WIP) Extremely fast JavaScript and TypeScript linter and Rust crate (by rslint)

    Project mention: Why isn't differential dataflow more popular? | | 2021-01-22


  • GitHub repo rust-csv

    A CSV parser for Rust, with Serde support.

    Project mention: Data Manipulation: Pandas vs Rust | | 2021-02-28

    Yep, I'll try to have a look at the nesting PR tonight, don't want to be a bitch, and not helping ahah :)

  • GitHub repo combine

    A parser combinator library for Rust

  • GitHub repo rust-peg

    Parsing Expression Grammar (PEG) parser generator for Rust

    Project mention: Hey Rustaceans! Got an easy question? Ask here (5/2021)! | | 2021-02-01

    The peg crate has a resolved issue about this.

  • GitHub repo lol-html

    Low output latency streaming HTML parser/rewriter with CSS selector-based API

    Project mention: Problems with building a backend app in Rust in 2020 | | 2020-12-21

    Cloudflare has open sourced lol-html, a "Low output latency streaming HTML parser/rewriter with CSS selector-based API". Is that what you are looking for?

  • GitHub repo git-journal

    The Git Commit Message and Changelog Generation Framework :book:

  • GitHub repo json-rust

    JSON implementation in Rust

  • GitHub repo pom

    PEG parser combinators using operator overloading without macros.

  • GitHub repo chomp

    A fast monadic-style parser combinator designed to work on stable Rust.

  • GitHub repo sv-parser

    SystemVerilog parser library fully complient with IEEE 1800-2017

  • GitHub repo fast-float-rust

    Super-fast float parser in Rust

    Project mention: Eisel-Lemire Algorithm | | 2021-02-07


  • GitHub repo oak

    A typed parser generator embedded in Rust code for Parsing Expression Grammars (by ptal)

  • GitHub repo bnf

    Parse BNF grammar definitions

  • GitHub repo pq

    a command-line Protobuf parser with Kafka support and JSON output (by sevagh)

    Project mention: Podman: A Daemonless Container Engine | | 2021-02-11

    I have a Makefile for a Rust project which binds the local repository to a Docker volume, builds it in the container using muslrust, and then does a chown to change the target directory back from root ownership to my own user.

    All I had to do was 's/docker/podman/g' and remove the chown hack and it works fine:

    It understands Dockerfiles and can pull images from Dockerhub.

  • GitHub repo lib-ruby-parser

    Ruby parser written in Rust

    Project mention: Artichoke Ruby Architecture | | 2021-02-12

    For now Artichoke leans on mruby’s parser, but I’m looking forward to using which is a Rust port of MRI’s parse.y.

  • GitHub repo endbasic

    BASIC environment with a REPL, a web interface, and RPi support written in Rust

    Project mention: EndBASIC: A retro-looking BASIC environment, now with Raspberry Pi support | | 2021-03-02

    Not a ton for now. Take a look at or open the web version in and type HELP.

  • GitHub repo mailparse

    Rust library to parse mail files

  • GitHub repo sax-wasm

    The first streamable, fixed memory XML, HTML, and JSX parser for WebAssembly.

    Project mention: Introducing check html links - no more bad links | | 2021-01-27

    I have been using sax-wasm in a few situations before and I knew it supported streaming. I knew that way it could be FAST 🤞!

  • GitHub repo queryst

    Rust query string parser with nesting support
