Iterates over all MemorySize enum values

impl MemorySize

pub fn info(self) -> &'static MemorySizeInfo

Examples

use iced_x86::*;
let info = MemorySize::Packed256_UInt16.info();
assert_eq!(info.size(), 32);

pub fn size(self) -> usize

Gets the size in bytes of the memory location or 0 if it’s not accessed by the instruction or unknown or variable sized

Examples

use iced_x86::*;
assert_eq!(MemorySize::UInt32.size(), 4);
assert_eq!(MemorySize::Packed256_UInt16.size(), 32);
assert_eq!(MemorySize::Broadcast512_UInt64.size(), 8);

pub fn element_size(self) -> usize

Gets the size in bytes of the packed element. If it’s not a packed data type, it’s equal to size().

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::Broadcast512_UInt64.element_type(), MemorySize::UInt64);

pub fn element_type_info(self) -> &'static MemorySizeInfo

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

Examples

use iced_x86::*;
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

true if this is a packed data type, eg. MemorySize::Packed128_Float32

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

Gets the number of elements in the packed data type or 1 if it’s not packed data (is_packed())

Examples

use iced_x86::*;
assert_eq!(MemorySize::UInt32.element_count(), 1);
assert_eq!(MemorySize::Packed256_UInt16.element_count(), 16);
assert_eq!(MemorySize::Broadcast512_UInt64.element_count(), 1);

impl MemorySize

pub fn is_broadcast(self) -> bool

Checks if it is a broadcast memory type

Examples
