A macro for defining static, type-safe detours.

This macro defines one or more StaticDetours.

Syntax

static_detour! {
  [pub] static NAME_1: [unsafe] [extern "cc"] fn([argument]...) [-> ret];
  [pub] static NAME_2: [unsafe] [extern "cc"] fn([argument]...) [-> ret];
  ...
  [pub] static NAME_N: [unsafe] [extern "cc"] fn([argument]...) [-> ret];
}

Example

static_detour! {
  // The simplest detour
  static Foo: fn();

  // An unsafe public detour with a different calling convention
  pub static PubFoo: unsafe extern "C" fn(i32) -> i32;

  // A specific visibility modifier
  pub(crate) static PubSelf: unsafe extern "C" fn();
}
