Struct Affinity 

pub struct Affinity {
    pub strength: Strength,
    pub target: Target,
    pub anti: bool,
}

A typed affinity constraint.

Examples

use grafos_std::affinity::{Affinity, Strength, Target};

// Required: place on node 42.
let a = Affinity::new(Strength::Required, Target::node(42));

// Preferred anti-affinity: avoid rack 7.
let b = Affinity::anti(Strength::Preferred, Target::rack(7));

// Required trust domain.
let c = Affinity::new(Strength::Required, Target::trust_domain("secure-enclave"));

Fields

strength: Strength

target: Target

anti: bool

Implementations

impl Affinity

pub fn new(strength: Strength, target: Target) -> Self

Create an affinity constraint (toward the target).

pub fn anti(strength: Strength, target: Target) -> Self

Create an anti-affinity constraint (away from the target).

Trait Implementations

impl Clone for Affinity

fn clone(&self) -> Affinity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Affinity

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

Formats the value using the given formatter.

impl PartialEq for Affinity

fn eq(&self, other: &Affinity) -> 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 Eq for Affinity

impl StructuralPartialEq for Affinity
