Macro concat_slices

macro_rules! concat_slices {
    ([$T:ty]: $($s:expr),* $(,)?) => { ... };
}

Concatenate const &[T] expressions into a static slice.

This macro takes any number of comma-separated &[T] expressions and yields an expression of type &'static [T] which is the result of all of the expressions concatenated left-to-right.

Notes

• This macro requires that the type of slice be specified before the comma separated expressions. This must be in the form [T]: where T is the the type.

  concat_slices!([usize]: /* ... */);

  concat_slices!([(u8, u8, u8)]: /* ... */);

• This also works for custom types as long as the type implement Copy.

  #[derive(Clone, Copy)]
  struct i256(i128, i128);
  
  concat_slices!([i256]: /* ... */);

See the crate documentation for examples.
