CXX
Safe interop between Rust and C++
CXX is a library that offers safe interop between Rust and C++. It provides a safe mechanism for calling C++ code from Rust and vice versa, one that is protected from the many possible things that can go wrong when bindgen or cbindgen is used to generate unsafe C-style bindings. The general idea of CXX is to define the signatures of both sides of the FFI boundary embedded together in one Rust module. CXX gets a complete picture from this of the boundary, and through it is able to perform static analyses against the types and function signatures, ensuring that both Rust's and C++'s invariants and requirements are upheld. CXX then emits the relevant extern "C" signatures on both sides through a pair of code generators. This is done together with any necessary static assertions needed for later in the build process to verify correctness. The result is an FFI bridge that operates at zero or negligible overhead, with no copying, serialization or memory allocation needed. -

rust_cmd_lib
Common rust command-line macros and utilities
rust_cmd_lib is a Rust library designed to make it easier to write shell-script–style tasks in Rust, blending the power and safety of Rust with the expressiveness of shell pipelines. It provides macros and utilities that let you spawn external processes, redirect input/output, and pipe commands together, all without invoking a shell. You can write something like run_cmd!(ls -l | grep foo > out.txt) in a more declarative style, rather than manually wiring up file descriptors, handles, and child processes. The library also supports features like variable substitution, scoped environment settings, and defining custom commands (functions) that behave like built-ins. It hides much of the boilerplate of std::process::Command when you're doing simple task automations, but still allows full flexibility when needed. Because it avoids launching a shell, it reduces some classes of security and quoting errors, while improving readability of scripting logic inside a Rust binary. -

Parser for Rust source code
Parser for Rust source code
Parser for Rust source code is a major Rust crate for parsing Rust source code (token streams) into a syntax tree (AST) that procedural macros can inspect or transform. The primary target is macro authors: you can parse TokenStreams into syn::File, syn::Item, syn::Expr, syn::Type, etc. It offers rich data structures, fine-grained parsing, span tracking (for error reporting), traversal and mutation APIs (visit, fold, visit_mut), printing back to tokens, and strong feature-gating so you only compile what you need. The documentation emphasises that while the crate is geared for procedural macros (and custom derives), some of the APIs may be of more general use. Using syn you can effectively write code that analyzes or generates Rust code at compile time. -

hyper for Rust
An HTTP library for Rust
hyper is a fast HTTP implementation written in and for Rust. A Client for talking to web services. A Server for building those web services. Blazing fast thanks to Rust. High concurrency with non-blocking sockets. HTTP/1 and HTTP/2 support. hyper is a relatively low-level library, meant to be a building block for libraries and applications. If you are looking for a convenient HTTP client, then you may wish to consider reqwest. If you are looking for a convenient HTTP server, then you may wish to consider warp. Both are built on top of this library. A Service lets you define how to respond to incoming requests. While it is possible to implement the trait directly, there are a few patterns that are common when using Hyper. We’ve included some helpers for when these patterns fit our needs. An echo server will listen for incoming connections and send back the request body as the response body on POST requests. -

DCV Color Primitives
DCV Color Primitives Library
DCV Color Primitives is a library to perform image color model conversion. Aware of the underlying hardware and supplemental cpu extension sets (up to avx2). Support data coming from a single buffer or coming from multiple image planes. Support non-tightly packed data. Support images greater than 4GB (64 bit). Convert an image from bgra to nv12 (single plane) format containing yuv in BT601. You might want to propagate errors to the caller function or mix with some other error types. So far, buffers were sized taking into account the image pixel format and dimensions; However, you can use a function to compute how many bytes are needed to store an image of a given format and size. If your data is scattered in multiple buffers that are not necessarily contiguous, you can provide image planes. To take into account data which is not tightly packed, you can provide image strides.
