Enum ArchVariant 

pub enum ArchVariant {
    V2,
    V3,
    V4,
}

Architecture variants, e.g., with support for different instruction sets

Variants

V2

Targets 64-bit Intel/AMD CPUs newer than Nehalem (2008). Includes SSE3, SSE4 and other post-2003 CPU instructions.

V3

Targets 64-bit Intel/AMD CPUs newer than Haswell (2013) and Excavator (2015). Includes AVX, AVX2, MOVBE and other newer CPU instructions.

V4

Targets 64-bit Intel/AMD CPUs with AVX-512 instructions (post-2017 Intel CPUs). Many post-2017 Intel CPUs do not support AVX-512.

Trait Implementations

impl Clone for ArchVariant

fn clone(&self) -> ArchVariant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArchVariant

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

Formats the value using the given formatter.

impl Display for ArchVariant

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

Formats the value using the given formatter.

impl FromStr for ArchVariant

type Err = ()

The associated error which can be returned from parsing.

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

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

impl Hash for ArchVariant

fn hash<__H: Hasher>(&self, state: &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 Ord for ArchVariant

fn cmp(&self, other: &ArchVariant) -> 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 ArchVariant

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

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