Module emf_core_base_rs::global::library

Global library api.

Example

use emf_core_base_rs::global::{LockToken, Unlock, library};
use emf_core_base_rs::library::{DEFAULT_HANDLE, Symbol};
use std::path::Path;
use std::ffi::CString;

let mut lock = LockToken::<Unlock>::lock();

let library_path = Path::new("path to my library");
let symbol_name = CString::new("add_function").unwrap();

let mut  library = library::load(&mut lock, &DEFAULT_HANDLE, &library_path)?;
let symbol: Symbol<extern "C" fn(i32, i32) -> i32> =
    library::get_function_symbol(
        &lock,
        &library,
        &symbol_name,
        |f| unsafe { std::mem::transmute(f) }
    )?;

assert_eq!(symbol.as_ref()(5, 8), 13);
