Type Definition moore_vhdl::ty2::PhysicalSubtype

type PhysicalSubtype<'t> = ScalarSubtype<'t, dyn PhysicalType, BigInt>;

A subtype of an integer type.

Methods

impl<'t> PhysicalSubtype<'t>

pub fn new(     mark: &'t TypeMark<'t>,     range: Range<BigInt> ) -> Option<PhysicalSubtype<'t>>

Create a new integer subtype.

Returns Some(...) if range is a subrange of the integer, or None otherwise.

Example

use moore_vhdl::ty2::{Type, TypeMark, PhysicalUnit, PhysicalBasetype, PhysicalSubtype, Range};
use moore_vhdl::common::name::get_name_table;

let ty = PhysicalBasetype::new(Range::ascending(-1000isize, 1000isize), vec![
    PhysicalUnit::primary(get_name_table().intern("fs", false), 1),
    PhysicalUnit::secondary(get_name_table().intern("ps", false), 1000, 1000, 0),
], 0);
let tm = TypeMark::new(
    get_name_table().intern("TIME", false),
    &ty,
);
let a = PhysicalSubtype::new(&tm, Range::ascending(0isize, 100isize)).unwrap();
let b = PhysicalSubtype::new(&tm, Range::descending(100isize, 0isize)).unwrap();

assert_eq!(format!("{}", a), "TIME range 0 to 100");
assert_eq!(format!("{}", b), "TIME range 100 downto 0");
