#[no_mangle]
pub extern "C" fn rust_add(x: i32, y: i32) -> i32 {x + y
}

• Cargo.toml

[package]
name = "pyrust"
version = "0.1.0"
edition = "2021"# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html[dependencies][lib]
name = "pyrust"
crate-type = ["cdylib"]

• 构建

cargo build --release

python调用ffi

• .so for Linux
• .dll for Windows
• .dylib for MacOS

import cffiffi = 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
