Duplicate rust-toolchain and rust-toolchain.toml (for compatibility?)

[zys864]

Duplicate rust-toolchain and rust-toolchain.toml in the crate.

This crate use both of them for compatibility?

Here is the doc from rustup book

In these cases the toolchain can be named in the project's directory in a file called rust-toolchain.toml or rust-toolchain. If both files are present in a directory, the latter is used for backwards compatibility. The files use the TOML format and have the following layout:

There is an issue with github-action actions-rs/toolchain: it does not recoganize the rust-toolchain.toml but just rust-toolchain.

It seems it has been fixed. I'm gonna remove the plain text one as I confirmed it is fixed.

Does not work yet.

But both exist in crates, only rust-toolchain works according to rustup book.

If both files are present in a directory, the latter is used for backwards compatibility
