}

A marker trait indicating that a type has an alignment over 1, and is therefore not safe to use in an unaligned context.

Associated Types

type Unaligned: Unaligned + Sized + Copy

An unaligned representation of this type. Usually a u8 array of the same size.

Provided Methods

fn is_aligned(u: &Self::Unaligned) -> bool

Determines whether an unaligned representation of this type is aligned.

fn as_unaligned(&self) -> &Self::Unaligned

Borrows the value as unaligned.

unsafe fn as_unaligned_mut(&mut self) -> &mut Self::Unaligned

Mutably borrows the value as unaligned.

fn as_aligned(u: &Self::Unaligned) -> Option<&Self>

Borrows an unaligned type as an aligned value.

Returns None if u is not aligned.

unsafe fn as_aligned_mut(u: &mut Self::Unaligned) -> Option<&mut Self>

Mutably borrows an unaligned type as an aligned value.

Returns None if u is not aligned.

unsafe fn as_aligned_unchecked(u: &Self::Unaligned) -> &Self

Borrows an unaligned type as an aligned value, without first checking the alignment.

Causes undefined behaviour if used improprly!

unsafe fn as_aligned_mut_unchecked(u: &mut Self::Unaligned) -> &mut Self

Mutably borrows an unaligned type as an aligned value, without first checking the alignment.

Causes undefined behaviour if used improprly!

fn unaligned(self) -> Self::Unaligned

Converts a value to its unaligned representation.

unsafe fn from_unaligned(u: Self::Unaligned) -> Self

Copies a value from its unaligned representation.
