Struct Size

pub struct Size { /* private fields */ }

Size of a type in bytes.

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 not a multiple of 8.

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) -> i128

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.

pub fn signed_int_min(&self) -> i128

pub fn signed_int_max(&self) -> i128

pub fn unsigned_int_max(&self) -> u128

Trait Implementations

The resulting type after applying the + operator.

fn add(self, other: Size) -> Size

Performs the + operation.

impl AddAssign for Size

fn add_assign(&mut self, other: Size)

Performs the += operation.

impl Clone for Size

fn clone(&self) -> Size

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Size

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Size

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Mul<Size> for u64

type Output = Size

The resulting type after applying the * operator.

fn mul(self, size: Size) -> Size

Performs the * operation.

impl Mul<u64> for Size

type Output = Size

The resulting type after applying the * operator.

fn mul(self, count: u64) -> Size

Performs the * operation.

impl Ord for Size

fn cmp(&self, other: &Size) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Size

fn eq(&self, other: &Size) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Size

fn partial_cmp(&self, other: &Size) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Sub for Size

type Output = Size

The resulting type after applying the - operator.

fn sub(self, other: Size) -> Size

Performs the - operation.

impl Copy for Size

impl Eq for Size

impl StructuralPartialEq for Size
