Dylink

Dylink provides a run-time dynamic linking framework for lazily evaluating shared libraries such as .dll files. When functions are loaded they are evaluated through a thunk for first time calls, which loads the function from it's respective library. Proceeding calls after initialization have no overhead or additional branching checks, as the thunk is replaced by the loaded function.

| Windows | Linux | MacOS | WASM | |:-------:|:-----:|:-----:|------| | YES | YES | YES | NO |

Usage

Add this to your Cargo.toml

toml [dependencies] dylink = "0.5"

Example

Below is a basic working example on how to use the macro on windows. For windows, the .dll file extension is optional, but still recommended.

```rust use dylink::dylink;

[dylink(name = "Kernel32.dll")]

extern "stdcall" { fn GetLastError() -> u32; fn SetLastError(_: u32); }

fn main() { unsafe { SetLastError(52); assert_eq!(52, GetLastError()); } } ```
