wrapgen
wrapgen
is a tool to automatically generate Rust wrappers around C functions called via FFI.
It will wrap pointer returns in an Option
and int
returns in a Result
.
As of now, wrapgen
only works if your functions adhere to the C convention of returning
0 on a successful run and another value otherwise.
How to use wrapgen
You can use wrapgen as a standalone binary:
wrapgen input.rs output.rs
where input.rs
contains one function declaration per line
or include it in your build.rs
