Add a clippy configuration file configuring the MSRV. Add a github
actions job to run clippy on CI.
Please note the job does _not_ use `--all-targets` because doing so
causes:
```
error[E0554]: `#![feature]` may not be used on the stable release channel
--> src/lib.rs:46:54
|
46 | #![cfg_attr(all(test, feature = "unstable"), feature(test))]
```
We currently build the docs as a separate CI job, we can however just do
it as part of the `Tests` job using the nightly toolchain.
Conditionally build the docs based on a `DO_DOCS` env var.
Note, uses `--cfg docsrs` so can only be built run with nightly toolchain.
I think this might take a while to resolve and we should move ahead with
1.58. Looks like the fresh release of 1.59 added LLVM 13.0 that broke
some things.
Disable problematic jobs that involve Github Actions caching or `cross`
whenever the environment is set to ACT. This allows running the CI
pipeline locally and hopefully speeds up PR cycle times by reducing
unexpected CI pipeline results.
Based on the original work by Justin Moon.
*MSRV unchanged from 1.29.0.*
When `std` is off, `no-std` must be on, and we use the [`alloc`](https://doc.rust-lang.org/alloc/) and core2 crates. The `alloc` crate requires the user define a global allocator.
* Import from `core` and `alloc` instead of `std`
* `alloc` only used if `no-std` is on
* Create `std` feature
* Create `no-std` feature which adds a core2 dependency to polyfill `std::io` features. This is an experimental feature and should be
used with caution.
* CI runs tests `no-std`
* MSRV for `no-std` is 1.51 or so
