Scott Waye (Nov 06 2021 at 14:03): Scott Waye (Nov 06 2021 at 14:03):I'm working on getting a c# lib.rs for witx-bindgen. Just started really and have a question about how to use the self.locals . In lowering I create a local that I need to "free" after the call, in the lifting. I guess I want to use self.locals.insert("pinnedArray"); to create the local but how do I get a reference to that in Instruction::ListCanonLift ?
Scott Waye (Nov 06 2021 at 14:09):I should add that I'm starting with the C implementation, so locals is locals: Ns, in its struct FunctionBindgen<'a> . I'm new to Rust in general, so not sure what I should be looking for. I mean some of this code is specific to the C implementation, but the general idea of wanting to use a local in the lowering and lifting I would think is universal.

Alex Crichton (Nov 08 2021 at 15:43):@Scott Waye I don't think there's much too strict about this, the locals idea was just me trying to make it easier to generate temporary names for variables for languages like C where everything needs to be unique. That's not necessarily required of all generators and it largely depends otherwise on the shape of the code that you're generating and the lanugage that you're generating for (I don't know enough about C# to say anything myself)
