Collection of general purpose meta tools.
Among other useful meta tools the module aggregates variadic constructors of collections. For example macro hmap!
for constructing a hash map.
use meta_tools::*;
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 );
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.
use meta_tools::*;
for_each!( dbg, "a", "b", "c" );
// generates
dbg!( "a" );
dbg!( "b" );
dbg!( "c" );
