I have a Rust project of ~5k lines and about 15 dependencies. Compiling this takes pretty long, so I used cargo -Z timings to see what was causing the bottlenecks. Basically, packages related to jsonrpc seem to increase the compile time a lot, but I'm only using jsonrpc in one function so I don't see why my entire project needs to wait for jsonrpc to compile.
Is there a way to reorganize my project so that the rest of the project can compile in parallel with jsonrpc and then the final jsonrpc part can compile at the end?
Right now, my project is organized like this:
Cargo.toml
src/bin/binary_a.rs
src/bin/binary_b.rs
src/lib.rs
src/jsonrpc_using_mod.rs
src/mod_a.rs
src/mod_b.rs
...
src/mod_z.rs
