Macro call_macro_with_tokens

macro_rules! call_macro_with_tokens {
    { $mac:ident } => { ... };
}

Invokes a macro with the supported token types.

Invokes the macro with the list of Token types as arguments in priority order, delimited by commas (including a trailing comma).

The following example creates a SupportedScalar supertrait that implements ScalarExt for each token:

use generic_simd::{call_macro_with_tokens, scalar::ScalarExt};

macro_rules! supported_scalars {
    { $($token:ty,)+ } => {
        trait SupportedScalar: Copy $(+ ScalarExt<$token>)* {}
    }
}

call_macro_with_tokens!{ supported_scalars }
