crates[_std]: Move to top level, redo directory structure This change reworks the repository directory structure and how we house crates. Previously, there were the following directories in play: - `//crates`: vendored no_std crates - `//crates_std`: vendored std crates - `//stub_crates/crates`: template project for std crate vendoring - `//stub_crates/crates_std`: template project for no_std crate vendoring We are keeping these directories, but changing their locations. The new locations are: - `//crates`: template project for no_std crate vendoring - `//crates/vendor`: vendored no_std crates - `//crates_std`: template project for std crate vendoring - `//crates_std/vendor`: vendored std crates Top level aliases will continue to exist where they are so that users can access crates via easy to use monikers (e.g. `//:cortex-m`). However, this makes for a clearer and simpler directory structure. Moreover, this helps us integrate Cargo GNaw which requires vendored crates to be in a subdirectory of the template project itself. While it is possible to modify Cargo GNaw to ignore this requirement, we borrow Cargo GNaw from the Fuchsia team and don't want to make too drastic or incompatible changes within it at the moment.

This is a repository to vendor and provide build rules for the third party crates that Pigweed's rust code depends on. Currently only Bazel build rules are provided.
std and no_stdThis repository provides two separate sets of crates. One for std environments and one for no_std environments. The set that is used is determined by the //:std_enabled constraint setting and defaults to std. To use no_std add @rust_crates//:no_std to your platform definition.
The list of vendored crates is defined by the dependencies listed in //crates/Cargo.toml and //crates_std/Cargo.toml. The contents of the //crates and //crates_std directories are generated by the //:crates_vendor and //:crates_vendor_std targets.
To update the vendored crates, build files, and aliases to match run the following commands from the top level directory of the repository:
bazel run //:crates_vendor -- --repin bazel run //:crates_vendor_std -- --repin cargo run -- --config config.toml > aliases.bzl
Licenses can be checked with cargo license -d in the appropriate stub_crate.
We keep this, and all Markdown files in this repository, in a consistent Markdown format using mdformat. To install and format, use the following commands:
pip install mdformat-gfm mdformat README.md
= note: collect2: fatal error: cannot find 'ld'
compilation terminated.
If you get the above error when running bazel run //:crates_vendor -- --repin, ensure lld is installed on your system. For instance, on Debian based systems:
sudo apt install lld
