Struggling with deno FFI due lack of documentation/examples

  Fastest JavaScript client for MySQL, with Deno FFI.

  

I'm trying to add missing bind params feature in https://github.com/denodrivers/mysql-native, but I can't find any examples/documentation how to define complex structs in Deno FFI. libysqlclient function mysql_stmt_bind_param() requires parameter MYSQL_BIND struct. how would one define it in parameters in Deno.dlopen()? Any pointers/help would be appreciated.

For struct passing the situation is such that Demo does not yet have support for passing structs by value. A PR is open and very close to being merged but struct passing is complex and it's not even fully clear if the libffi crate being used to implement FFI calls internally has all the things related to struct passing implemented correctly. The PR is here if you're interested: https://github.com/denoland/deno/pull/15060
