ci: some meta files may not be respected

[Xuanwo]

          I found a new issue that some meta files may not be respected:

• rust-toolchain.toml
• rustfmt.toml
• deny.toml

... when run cargo xxx for a specific package now; due to the change of folder structure?

Hi, @tisonkun

Config files like rust-toolchain.toml are often finding from current dir to the root.

The toolchain is chosen in the order listed above, using the first one that is specified. There is one exception though: directory overrides and the rust-toolchain.toml file are also preferred by their proximity to the current directory. That is, these two override methods are discovered by walking up the directory tree toward the filesystem root, and a rust-toolchain.toml file that is closer to the current directory will be preferred over a directory override that is further away.

Can you show the cargo command and the specific package you check?

[tisonkun]

Make sense. I should get a wrong understanding about the compilation failure -

How about rustfmt.toml and deny.toml?

[Xuanwo]

For rustfmt.toml:

You can create a TOML file called rustfmt.toml or .rustfmt.toml, place it in the project or any other parent directory and it will apply the options in that file.

ref: https://rust-lang.github.io/rustfmt/?version=v1.6.0&search=

For deny.toml:

https://github.com/EmbarkStudios/cargo-deny/blob/3afa5e50698271eab5fee24e841de3e81cbe1771/src/cargo-deny/common.rs#L69-L104

deny will find till root.

Confirmed it works, let's close.
