Enum IntTy 

#[repr(u8)]
pub enum IntTy {
    I8 = 0,
    I16 = 1,
    I32 = 2,
    I64 = 3,
    U8 = 4,
    U16 = 5,
    U32 = 6,
    U64 = 7,
}

An integer type: the width and signedness an integer instruction works at (OPS §1).

Examples

use bytecode_lang::IntTy;

assert_eq!(IntTy::I64.bits(), 64);
assert!(IntTy::I8.is_signed());
assert!(!IntTy::U32.is_signed());
assert_eq!(IntTy::from_code(3), Some(IntTy::I64));
assert_eq!(IntTy::U16.to_string(), "u16");

Variants

I8 = 0

Signed 8-bit.

I16 = 1

Signed 16-bit.

I32 = 2

Signed 32-bit.

I64 = 3

Signed 64-bit.

U8 = 4

Unsigned 8-bit.

U16 = 5

Unsigned 16-bit.

U32 = 6

Unsigned 32-bit.

U64 = 7

Unsigned 64-bit.

Implementations

impl IntTy

pub const ALL: &'static [IntTy]

Every value, in code order.

pub const fn from_code(code: u8) -> Option<Self>

The value with this stable code, or None if no value has it.

pub const fn code(self) -> u8

The stable code this value is encoded as.

pub const fn name(self) -> &'static str

The lowercase name the disassembler prints.

impl IntTy

pub const fn bits(self) -> u32

The width in bits: 8, 16, 32, or 64.

Examples

use bytecode_lang::IntTy;

assert_eq!(IntTy::U16.bits(), 16);

pub const fn is_signed(self) -> bool

Whether the type is two’s-complement signed.

Examples

use bytecode_lang::IntTy;

assert!(IntTy::I32.is_signed());
assert!(!IntTy::U8.is_signed());
