If you've used RUST_LOG to enable logging for Rust modules, but were hoping you could filter down to child processes only, bug 1390736 now allows you to use RUST_LOG_CHILD to target them. This has been helpful for several of us working on Stylo.
To use, just replace RUST_LOG with RUST_LOG_CHILD and supply the same filtering and log levels as usual. In the process, I also wrote some notes about Rust logging in general on the Gecko logging page[1]. If there are other env vars like this that would be helpful to target per process / process type, let's discuss it! There might be a need for something more general than this one-off addition.
