Just started learning Rust today and got Rust installed, got the hello world example compiled and running. I installed rust-analyzer
and CodeLLDB
extensions in VSCode. Enable the debug.allowBreakpointsEverywhere
settings to VSCode to be true. Setup a debug configuration in VSCode.
However I keep getting errors from rust-analyzer
when I run the debugger...
2024-10-06T22:16:04.808655Z ERROR FetchWorkspaceError: rust-analyzer failed to load workspace: Failed to load the project at /home/john/Documents/Snippets/Rust/Cargo.toml: Failed to read Cargo metadata from Cargo.toml file /home/john/Documents/Snippets/Rust/Cargo.toml, Some(Version { major: 1, minor: 81, patch: 0 }): Failed to run `cd "/home/john/Documents/Snippets/Rust" && RUSTUP_TOOLCHAIN="/home/john/.rustup/toolchains/stable-x86_64-unknown-linux-gnu" "/home/john/.cargo/bin/cargo" "metadata" "--format-version" "1" "--manifest-path" "/home/john/Documents/Snippets/Rust/Cargo.toml" "--filter-platform" "x86_64-unknown-linux-gnu"`: `cargo metadata` exited with an error: error: failed to parse manifest at `/home/john/Documents/Snippets/Rust/Cargo.toml`
Caused by:
no targets specified in the manifest
either src/lib.rs, src/main.rs, a [lib] section, or [[bin]] section must be present
I not sure how to fix this.
I would like to get the VSCode debugger to work for launch debugging, attach debugging and launch and attach debugging for rust running inside a docker container. This will be a good setup for getting started I believe.
This is my VSCode debugger configuration...

Any help and advice will be most appreciated.
I think you're tying yourself too close to VSCode. Reading this Cargo guide is a minimal requirement. And you should learn how to use
cargo
(the command), at least for basic operations. This is not hard. If anything, it's much simpler than those bloated and opaque editor/IDE setups.Maybe should be mentioned, if you just run
cargo run
in the project repo, you should get the same error without all the noise surrounding it...
