Examples

use iced_x86::*;
assert_eq!(MemorySize::UInt32.element_size(), 4);
assert_eq!(MemorySize::Packed256_UInt16.element_size(), 2);
assert_eq!(MemorySize::Broadcast512_UInt64.element_size(), 8);

pub fn element_type(self) -> Self

Gets the element type if it’s packed data or self if it’s not packed data

Examples

use iced_x86::*;
assert_eq!(MemorySize::UInt32.element_type(), MemorySize::UInt32);
assert_eq!(MemorySize::Packed256_UInt16.element_type(), MemorySize::UInt16);

assert_eq!(MemorySize::UInt32.element_type_info().memory_size(), MemorySize::UInt32);
assert_eq!(MemorySize::Packed256_UInt16.element_type_info().memory_size(), MemorySize::UInt16);
assert_eq!(MemorySize::Broadcast512_UInt64.element_type_info().memory_size(), MemorySize::UInt64);

pub fn is_signed(self) -> bool

true if it’s signed data (signed integer or a floating point value)

Examples

use iced_x86::*;
assert!(!MemorySize::UInt32.is_signed());
assert!(MemorySize::Int32.is_signed());
assert!(MemorySize::Float64.is_signed());

pub fn is_packed(self) -> bool

Examples

use iced_x86::*;
assert!(!MemorySize::UInt32.is_packed());
assert!(MemorySize::Packed256_UInt16.is_packed());
assert!(!MemorySize::Broadcast512_UInt64.is_packed());

pub fn element_count(self) -> usize
