Struct rustc_abi::Align

pub struct Align {
    pub(crate) pow2: u8,
}

Alignment of a type in bytes (always a power of two).

Fields

pow2: u8

Implementations

impl Align

pub const ONE: Align = _

pub const MAX: Align = _

pub fn from_bits(bits: u64) -> Result<Align, String>

pub fn from_bytes(align: u64) -> Result<Align, String>

pub fn bytes(self) -> u64

pub fn bits(self) -> u64

pub fn max_for_offset(offset: Size) -> Align

Computes the best alignment possible for the given offset (the largest power of two that the offset is a multiple of).

N.B., for an offset of 0, this happens to return 2^64.

pub fn restrict_for_offset(self, offset: Size) -> Align

Lower the alignment, if necessary, such that the given offset is aligned to it (the offset is a multiple of the alignment).

Trait Implementations

impl Clone for Align

fn clone(&self) -> Align

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Align

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

Formats the value using the given formatter.

impl<__D: Decoder> Decodable<__D> for Align

fn decode(__decoder: &mut __D) -> Self

impl<__E: Encoder> Encodable<__E> for Align

fn encode(&self, __encoder: &mut __E)

impl Hash for Align

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<__CTX> HashStable<__CTX> for Alignwhere
    __CTX: HashStableContext,

fn hash_stable(&self, __hcx: &mut __CTX, __hasher: &mut StableHasher)

impl Ord for Align

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Align> for Align

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<Align> for Align

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
