Struct vectorscan::flags::platform::Platform

pub struct Platform {
    pub tune: TuneFamily,
    pub cpu_features: CpuFeatures,
}

Available on crate feature compiler only.

A collection of bitsets used for instruction selection.

In particular this configuration is consumed by the various pattern compilers. See Database#Platform Compatibility for further reference.

Fields

tune: TuneFamily

Tuning flags.

cpu_features: CpuFeatures

CPU feature support flags.

Implementations

impl Platform

pub fn local() -> Result<Self, VectorscanRuntimeError>

Configuration to build for the current platform.

This method calls into hs_populate_platform() to populate the returned platform struct with all the features the currently executing processor has access to when building a database.

pub const GENERIC: Self = _

Configuration to build for the most general possible database target.

This will produce a maximally compatible database when deserialized, but won’t be able to take advantage of any specialized instructions.

Trait Implementations

impl Clone for Platform

fn clone(&self) -> Platform

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Platform

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

Formats the value using the given formatter.

impl Default for Platform

fn default() -> Platform

Returns the “default value” for a type.

impl Hash for Platform

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 Platform

fn cmp(&self, other: &Platform) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Platform

fn eq(&self, other: &Platform) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Platform

fn partial_cmp(&self, other: &Platform) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
