libloader is a easy-to-use DLL loader for rust that based on libloading
It is very easy to dynamically call a function from dynamic link library (DLL files for Windows, so files for Unix/Linux dylib for macOS )
Use this function to get the function from DLL
rust
get_libfn!(
"path.dll",
"func_name",
name_to_call,
return_type, // ifreturn type is none, use "()" instead
param1_name: param1_type
param2_name: param2_type
param3_name: param3_type
...
);
For example, We have these functions from libstd.dylib
```rust
// lib.rs （compiled into libstd.dylib)
pub fn println(str: &str) { println!("{}", str); }
pub fn add(a: usize, b: usize) -> usize { a + b }
pub fn print_hello() { println!("Hello"); }
We can call it with:
//
// main.rs
fn main() {
getlibfn!("libstd.dylib", "println", myprintln, (), str: &str);
my_println("Hello World");
get_libfn!("libstd.dylib", "add", my_add, usize, a: usize, b: usize);
println!("10 + 20 = {}", my_add(10, 20));
get_libfn!("libstd.dylib", "print_hello", my_print_hello, ());
my_print_hello();
} ```
