Struct Alignment 

pub struct Alignment {
    pub power: u8,
}

Alignment of a type or value.

It is stored as its power of two, so the compiler knows that the alignment in bytes is a power of two, and code that uses it can compute padding with plain % that compiles to bit masks. Alignments compare like their values in bytes.

Fields

power: u8

Power of two of the alignment, at most the power of Alignment::MAX

Implementations

impl Alignment

pub const MAX: Self

The largest alignment supported, 16 bytes.

No TrivialType has a larger alignment.

pub const fn from_power(power: u8) -> Option<Self>

Alignment from its power of two, None if it would be larger than Alignment::MAX

pub const fn of<T>() -> Self

where T: TrivialType,

Alignment of T in metadata, see TrivialType::ALIGNMENT.

TrivialType requires an alignment of at most Alignment::MAX, and a call doesn’t compile for an implementation that breaks this requirement. It also doesn’t compile when T::ALIGNMENT is smaller than align_of::<T>().

pub const fn get(self) -> u8

The alignment in bytes

pub fn is_slice_aligned<T>(self, slice: &[T]) -> bool

where T: TrivialType,

Whether slice starts at an address aligned to self

Trait Implementations

impl PartialOrd for Alignment

fn partial_cmp(&self, other: &Alignment) -> 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.
