pub extern "C" fn rust_add(x: i32, y: i32) -> i32 {
x + y
}
Cargo.toml
[package]

构建
cargo build --release
python调用ffi
.so for Linux.dll for Windows.dylib for MacOS
import cffi
ffi = cffi.FFI()
ffi.cdef(
"""
int rust_add(int x, int y);
"""
)
C = ffi.dlopen('./pyrust/target/release/pyrust.dll')
res = C.rust_add(12, 5)
print(res)
python main.py
