How do I set Rust-Analyzer to do all features?

[Multirious]

[[language]]
name = "rust"

[language.config]
cargo = { extraArgs = ["--all-features"], features = "all", allFeatures = true  }
check = { extraArgs = ["--all-features"] }

I've tried all of these at the same time and any of these with any combination in my .helix/languages.toml in my project directory.
I've insert some random invalid args and Rust-Analyzer did crashed so I know that it is listening.

[Multirious]

Does anyone have any config that works?

[kirawi]

cargo.allFeatures = true worked fine for me

Where do you set this?

you can try my answer: #7787 (comment)

You can make use of rust-analyzer.cargo.features. You can add this to your language.toml file:

[language-server.rust-analyzer]
config = { cargo = { features = "all" } }

[Multirious]

I've tried everything including this. I've just now tested this again with the above config in version helix 23.10 (f6021dd0) and the problem still persisted.
The message is code is inactive due to #[cfg] directives: feature = "..." is disabled

I also tried

[language-server.rust-analyzer]
config = { cargo = { features = ["a_feature"] } }

and it doesn't seem to works too?

[TornaxO7]

May I ask where you have put this?

[language-server.rust-analyzer]
config = { cargo = { features = ["a_feature"] } }

Do you have an entry of rust-analyzer where you renamed it, hence language-server.rust-analyzer should be something like language-server.rust?
Could you please post your config?

I tried and get the same result as Multirious (helix 23.10 (f6021dd)). I have put the above configuration in the project directory in .helix/languages.toml.

My global languages.toml looks like this:

[[language]]
name = "rust"

[language.debugger]
name = "lldb-vscode"
transport = "stdio"
command = "lldb-vscode"

[[language.debugger.templates]]
name = "binary"
request = "launch"
completion = [ { name = "binary", completion = "filename" } ]
args = { program = "{0}", initCommands = [ "command script import /usr/local/etc/lldb_vscode_rustc_primer.py" ] }

Here is a working config:

[[language]]
name = "rust"
auto-format = true
#
[language-server.rust-analyzer]
config = { checkOnSave = { command = "clippy" }, cargo = { allFeatures = true }}
