Type Definition moore_vhdl::ty2::EnumSubtype [−][src]
pub type EnumSubtype<'t> = ScalarSubtype<'t, dyn EnumType, usize>;
Expand description
A subtype of an enumeration type.
Implementations
Create a new enumeration subtype.
Example
use moore_vhdl::ty2::{Type, TypeMark, EnumBasetype, EnumSubtype, Range};
use moore_common::name::get_name_table;
let ty = EnumBasetype::new(vec![
"first".into(),
"second".into(),
'0'.into(),
'1'.into(),
]);
let tm = TypeMark::new(
get_name_table().intern("MY_TYPE", false),
&ty,
);
let subty = EnumSubtype::new(&tm, Range::ascending(1usize, 2usize)).unwrap();
assert_eq!(format!("{}", subty), "MY_TYPE range second to '0'");
