Struct PointerAlignSpec

#[non_exhaustive]
pub struct PointerAlignSpec {
    pub address_space: AddressSpace,
    pub abi_alignment: Align,
    pub preferred_alignment: Align,
    pub pointer_size: u64,
    pub index_size: u64,
}

Represents a pointer width (in bits), along with its ABI-mandated and preferred alignments (which may differ).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

address_space: AddressSpace

The address space that this pointer specification is valid in.

abi_alignment: Align

The ABI-enforced alignment for this pointer.

preferred_alignment: Align

The preferred alignment for this pointer.

Like TypeAlignSpec, this is enforced by construction to be no less than the ABI-enforced alignment.

pointer_size: u64

The size of this pointer type, in bits.

index_size: u64

The size of indexing operations with this pointer type, in bits.

Implementations

impl PointerAlignSpec

pub fn new( address_space: AddressSpace, abi_alignment: Align, preferred_alignment: Align, pointer_size: u64, index_size: u64, ) -> Result<Self, AlignSpecError>

Create a new PointerAlignSpec.

Trait Implementations

impl Clone for PointerAlignSpec

fn clone(&self) -> PointerAlignSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PointerAlignSpec

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

Formats the value using the given formatter.

impl Default for PointerAlignSpec

fn default() -> Self

Returns the “default value” for a type.

impl FromStr for PointerAlignSpec

type Err = AlignSpecError

The associated error which can be returned from parsing.

fn from_str(value: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Ord for PointerAlignSpec

fn cmp(&self, other: &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 PartialEq for PointerAlignSpec

fn eq(&self, other: &PointerAlignSpec) -> 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 PointerAlignSpec

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