Crate meta_tools_min

Collection of general purpose meta tools. Minimal Set.

Module :: meta_tools

Collection of general purpose meta tools.

Sample :: variadic constructor of collections

Among other useful meta tools the module aggregates variadtic constructors of collections. For example macro hmap! for constructing a hash map.

#[ cfg( feature = "collection_make" ) ]
{
  use meta_tools_min::*;

  let meta_map = hmap! { 3 => 13 };
  let mut std_map = std::collections::HashMap::new();
  std_map.insert( 3, 13 );
  assert_eq!( meta_map, std_map );
}

Sample :: function-style call

Apply a macro for each element of a list.

Macro for_each may be called either in function-style way or in map-style way. Pass name of macro to apply to elements as the first arguments and elements after the macro name. Use comma as delimiter.

#[ cfg( feature = "for_each" ) ]
{
  use meta_tools_min::*;
  for_each!( dbg, "a", "b", "c" );

  // generates
  dbg!( "a" );
  dbg!( "b" );
  dbg!( "c" );
}
