libs-team VS crates.io

In rust, both release and debug builds use a release version of the runtime. The bugs the debug version is meant to catch are much more difficult to hit in rust (often but not always requiring unsafe). There isn't currently a feature to use the debug runtime in rust-- you can only change C to match for those debug builds.

Note that this has been discussed at length (and I do mean "at length") here: https://github.com/rust-lang/libs-team/issues/72

The Compiler Team, especially the Diagnostics Working Group that improves compiler error messages. The Libs Team, for work on the contents of the standard library documentation

See https://github.com/rust-lang/libs-team/issues/72#issuecommen... for what I believe is an exhaustive list of possible ways of helping the situation.

The point is how the MSRV of a popular crate affects this dynamic for other crates. For an even more extreme example than time, see here for libc, with many heavyweights offering opinions: https://github.com/rust-lang/libs-team/issues/72

In case you haven't seen it yet, there is a very long discussion surrounding MSRV policy of the libc crate on rust-langs github repo. It's about a library, not a binary, but I think there's a lot of information in the thread, some of which will also apply to binaries.

Would you mind sharing your use case for being stuck with a particular version of Rust and why you can't upgrade? In particular with the libs team: https://github.com/rust-lang/libs-team/issues/72

Compare Stepanov's brilliant design of the STL to Rust's current reworking of their 'binary search api'. https://github.com/rust-lang/libs-team/issues/81

Maybe 'memory safety' isn't the most important thing in this world. To me, writing software that does useful things in the simplest and most correct way is what matters. I get the feeling it's harder to understand my program's correctness with Rust (I mean algorithmic correctness). The C++ standard library has time and space complexity for every algorithm. I'm not seeing that's the case with Rust (correct me if I'm wrong).

There's also the pretty fundamental libc crate that wants to choose an MSRV policy and you can see the full discussion here: https://github.com/rust-lang/libs-team/issues/72

Rust has a rich ecosystem of frameworks and libraries that let you read, parse, and manipulate text files, interact with cloud services and databases, and perform any other job that your project's development workflow may require. And because of its strong typing and tight memory management, you are much less likely to write programs that behave unexpectedly in production.

All the code discussed in this article can be accessed through this repository. For integration with existing projects consider using keyword_extraction crate available on crates.io.

So, be sure to double-check your critical libraries and be sure their alternatives exist in the Rust ecosystem. There’s a good chance the crates you need are available in Rust's crates.io repository.

The previous section was very simple, this section is also very simple but introduces us to cargo which is Rust's package manager, as a JS dev my mind goes straight to NPM.

Now, there has to be a place where all these packages come from. Similar to npmjs registry, where all node packages are registered, stored and retrieved, Rust also has something called crates.io where many helpful packages and dependencies are registered.

Before proceeding, let's check https://crates.io/, the official Rust package registry.

The most thrilling aspect has been the joy of writing the backend. It's like every struct, enum, and method in Rust forms this interconnected Multiverse of code , which you can see in crates.io which is best Documentation experience I Ever Had.

5. Crates.io

When using crates from eg. crates.io, and also things like std and core

Vendoring your packages was very tedious to even remotely get to work with Cargo. I spent a very long time getting Cargo to work together with cargo-local-registry. We vendor crates from crates.io and a custom internal registry.
