Structs and functions with parameters/fields named "handle" are quietly not exported

[LukasBoersma]

Hi, I think I caught a bug in witgen. When I run cargo witgen generate on this code:

use witgen::witgen;

#[witgen]
fn works() {}

#[witgen]
fn doesnt_work(handle: i32) -> i32 { handle }

#[witgen]
struct Works { test: i32 }

#[witgen]
struct DoesntWork { handle: i32 }

Then it creates this WIT file:

// auto-generated file by witgen (https://github.com/bnjjj/witgen), please do not edit yourself, you can generate a new one thanks to cargo witgen generate command. (cargo-witgen v0.15.0) 

works: func()


record works {
  test: s32
}

The function doesnt_work and the struct DoesntWork are missing.

There is no error being reported from the cargo witgen generate command.

I am using cargo-witgen v0.15.0, the witgen crate is also v0.15.0.

Good catch! It seems that handle is not a keyword anymore.

Will update soon!
