ruster

Ruster is a library using ffi for database management with psql/pg_dump + mysql/mysqldump written in Rust.

The generated C static and shared libraries can be reused in other languages (Golang for example).

Build ruster

The build of project produces 2 go binaries, 1 static library (libruster.a) and 1 shared library (libruster.so).

The headers of C functions are in lib/ruster.h and must be present before code generation.
