Struct rustc_target::abi::Size

pub struct Size {
    raw: u64,

Size of a type in bytes.

Fields

raw: u64

Implementations

impl Size

pub const ZERO: Size

pub fn from_bits(bits: impl TryInto<u64>) -> Size

Rounds bits up to the next-higher byte boundary, if bits is is not aligned.

pub fn from_bytes(bytes: impl TryInto<u64>) -> Size

pub fn bytes(self) -> u64

pub fn bytes_usize(self) -> usize

pub fn bits(self) -> u64

pub fn bits_usize(self) -> usize

pub fn align_to(self, align: Align) -> Size

pub fn is_aligned(self, align: Align) -> bool

pub fn checked_add<C: HasDataLayout>(self, offset: Size, cx: &C) -> Option<Size>

pub fn checked_mul<C: HasDataLayout>(self, count: u64, cx: &C) -> Option<Size>

pub fn sign_extend(self, value: u128) -> u128

Truncates value to self bits and then sign-extends it to 128 bits (i.e., if it is negative, fill with 1’s on the left).

pub fn truncate(self, value: u128) -> u128

Truncates value to self bits.
