Enum Strength 

pub enum Strength {
    Weak,
    Medium,
    Strong,
    Required,
}

Constraint strength. Required rules are hard: a solution violating them is never accepted. The others are preferences ordered by priority.

Variants

Weak

Weak preference.

Medium

Medium preference.

Strong

Strong preference (drag targets use this).

Required

Hard rule.

Implementations

impl Strength

pub const fn weight(self) -> f64

Least-squares weight for the numeric backend (not squared). Hard rules are constraints, not weights; the bounded 10× ladder keeps the KKT system well conditioned (ADR-0004).

Trait Implementations

impl Clone for Strength

fn clone(&self) -> Strength

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Strength

impl Debug for Strength

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

Formats the value using the given formatter.

impl Default for Strength

fn default() -> Strength

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Strength

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Strength

impl Hash for Strength

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 Strength

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

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

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

impl Serialize for Strength

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
