Enum Alignment

pub enum Alignment {
    Pointer,
    Bytes(NonZeroUsize),
}

Architecture specific alignment

Variants

Pointer

This represents 4 byte alignment on 32bit and 8 byte alignment on 64bit architectures

Bytes(NonZeroUsize)

This alignment is architecture independent (derived from integer or float types)

Implementations

impl Alignment

pub fn align_wasm32(&self) -> usize

for easy migration this gives you the value for wasm32

pub fn align_wasm64(&self) -> usize

pub fn format(&self, ptrsize_expr: &str) -> String

Trait Implementations

impl Clone for Alignment

fn clone(&self) -> Alignment

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Alignment

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

Formats the value using the given formatter.

impl Default for Alignment

fn default() -> Self

Returns the “default value” for a type.

impl From<Alignment> for ArchitectureSize

fn from(align: Alignment) -> Self

Converts to this type from the input type.

impl From<Alignment> for ElementInfo

fn from(align: Alignment) -> Self

Converts to this type from the input type.

impl Ord for Alignment

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

Needed for determining the max alignment of an object from its parts. The ordering is: Bytes(1) < Bytes(2) < Bytes(4) < Pointer < Bytes(8) as a Pointer is either four or eight byte aligned, depending on the architecture

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 Alignment

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

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.
