orderless!

orderless generates macros for you that allow you to use orderless/named functions in Rust.

#[make_orderless(defs(a = 2, b))]
fn add(a: usize, b: usize) -> usize {
	a + b
}

// Compiles to add(2, 2) for no runtime performance hit!
add!(b = 2); // 4

Features

• Attribute macro.
• Procedural macro.
• Paths to functions (functions from crates and impl).
• Default argument values.
  • Identifiers.
  • Expressions.
  • const and static variables.
  • Optionally don't provide a default value.
• Shortcut identical name and value to just the name. a = a to a.
