Union AlignAs 

pub union AlignAs<T: Copy, A: Copy> {
    /* private fields */
}

Wrap an object of type T to give it the alignment requirements of an object of type A.

This has a similar effect to #[repr(align(…))], but is parameterized to support the creation of structures that are generic over alignment.

Example:

extern crate alignas;
use alignas::AlignAs;
use std::{mem, slice};

// put some byte data into the buffer
let mut buffer: AlignAs<_, u64> = AlignAs::new([0u8; 64]);
buffer[3..18].copy_from_slice(b"some input here");

// now do something with it that requires aligned access...
let mut ints = [0u64; 8];
let ptr = &buffer as *const _ as *const u64;
ints.copy_from_slice(unsafe { slice::from_raw_parts(ptr, 8) });

fn default() -> Self

Returns the “default value” for a type.

impl<T: Copy, A: Copy> Deref for AlignAs<T, A>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T: Copy, A: Copy> DerefMut for AlignAs<T, A>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<T: Hash + Copy, A: Copy> Hash for AlignAs<T, A>

fn hash<H: Hasher>(&self, h: &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<T: Ord + Copy, A: Copy> Ord for AlignAs<T, A>

fn cmp(&self, rhs: &Self) -> 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<T: PartialEq + Copy, A: Copy> PartialEq for AlignAs<T, A>

fn eq(&self, rhs: &Self) -> 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.

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.
