FFI

You can build the Warp Sync library as a dynamic library and use it from your code as long as it supports interfacing with native code.

Most programming languages have the ability to call into C code. Therefore, you should be able to use FFI (Foreign Function Interface).

In this section, we’ll describe the low-level C API.

Build

• First edit the file Cargo.toml and change the library type from rlib to cdylib
• Then compile:

cargo b -r --features=dart_ffi

This should create a dynamic library in the target/release directory. On Linux, the file is named libwarp_api_ffi.so. Other platforms have slightly different names.

Even if your programming language is not DART, the feature is dart_ffi for historical reasons.

Header file

The C header file is binding.h
