This is a simple crate that lets us scan one or all crates in the current workspace.
We can also use it to scan a vendored crate.
This helps us search a crate directly for trait, fn, struct, enum, type names, and macro defs.
This crate uses the rust-analyzer API to perform the heavy lifting.
I typically use it like this:
Cargo.toml
[build-dependencies]
scan-crate-for-typedefs = "0.6.0"
``rust
//this is thebuild.rs` file for one of the most
// stable crates in the workspace:
use scancratefor_typedefs::*;
fn main() -> std::io::Result<()> {
let typemap = PersistentWorkspaceTypeMap::new_with_path("..")?;
Ok(())
} ```
Then, all we have to do is build the project and
we get a rust-workspace-typemap.json at the
top-level
I typically parse the output of cargo build to find types which cannot be found.
Next, I scan the index contained within file to figure out which crate they belong to.
