Provides the procedural macro bounded_integer!
for generating enums for the
bounded-integer
crate.
Syntax
The syntax parsed by bounded_integer!
is roughly equivalent to the following
macro_rules!
-like matcher.
$(#[$attr:meta])*
$(pub)? enum $name:ident: $repr:ident { $min:expr...$max:expr }
Which expands to the following:
$(#[$attr:meta])*
#[derive(Clone, Copy, PartialEq, Eq, PartialOrd, Ord)]
#[repr($repr)]
$(pub)? enum $name { ... }
bounded_integer_impls!($name, $repr, ..., ...);
Where ...
are variants of the form ...N1, Z0, P1...
.
Note that the bounded_integer_impls!
macro is provided by the bounded-integer
crate.
