Subcommand to show result of macro expansion (by dtolnay)
sccache
Sccache is a ccache-like tool. It is used as a compiler wrapper and avoids compilation when possible. Sccache has the capability to utilize caching in remote storage environments, including various cloud storage options, or alternatively, in local storage. (by mozilla)

Why dereferencing coercion is not used here?
Try installing cargo expand, it's useful to see how macros eventually get expanded. For example, if you run cargo expand on the following code

[blog] Rust should own its debugger experience
Not too familiar with macros but does cargo-expand do what you want or did you mean something else?
-
Help me understand the borrowing and moving variable concept!
Yes. You can use Tools > Expand Macro on the playground or install and run cargo-expand to see what the macro expands to. It just adds a & before the argument.

How to see macro's source code in crate?
Along with what others are saying, there is also cargo expand which can show you what code a macro generates

How does Rust Python ffi work?
Something that may help you understand code with magic proc macros is this utility. It's basically a wrapper around a Rust compiler flag that allows you to expand macros for a file.

Speeding up C++ build times
Use icecream or sccache. sccache supports distributed builds.

Mozilla sccache: cache with cloud storage
Worth noting that the first commit in sccache git repository was in 2014 (https://github.com/mozilla/sccache/commit/115016e0a83b290dc2...). So I suppose that what "happened" happened waay back.

Target file are very huge and running out of storage on mac.
If you have lots of shared dependencies, maybe try sccache?

S3 Express Is All You Need
I'm going to set up sccache [0] to use it tomorrow. We use MSVC, so EFS is off the cards.

Serde has started shipping precompiled binaries with no way to opt out
I think the primary benefit of pre-built procmacros will be for build servers which don't use a persistent cache (like sccache), since they have to compile all dependencies every time. But IMO improved support for persistent caches would be a better investment compared to adding support for pre-built procmacros.

Distcc: A fast, free distributed C/C++ compiler
https://github.com/mozilla/sccache is another option which addresses the use cases of both icecream and ccache (and also supports Rust, and cloud storage of artifacts, if those are useful for you)

How to fix Rust Coding LARGE files????
That being said a compilation cache, eg the de-facto standard for Rust: sccache (https://github.com/mozilla/sccache) will help to compile and store some of the build artifacts centralized - still for each crate version + build profile (RUSTFLAGS) combination.
