Struct Variable 

pub struct Variable {
    pub value: f64,
    pub fixed: bool,
    pub scale: f64,
    pub label: String,
    pub stay: f64,
}

A solver variable.

Fields

value: f64

Current (starting) value.

fixed: bool

Fixed variables are constants for this solve (locks, fix rules on params).

scale: f64

Characteristic magnitude used to scale steps (mm for lengths, 1 for angles).

label: String

Diagnostic label ("e12.width").

stay: f64

Multiplier of the stay preference (how strongly this variable keeps its previous value relative to others), clamped to [0.1, 5].

Implementations

impl Variable

pub fn new(value: f64) -> Self

Free variable with scale 1.

pub fn stay(self, s: f64) -> Self

Builder: stay multiplier.

pub fn scale(self, s: f64) -> Self

Builder: scale.

pub fn fixed(self, f: bool) -> Self

Builder: fixed flag.

pub fn label(self, l: impl Into<String>) -> Self

Builder: label.

Trait Implementations

impl Clone for Variable

fn clone(&self) -> Variable

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Variable

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Variable

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Variable

fn eq(&self, other: &Variable) -> 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 Serialize for Variable

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
