Struct PointExpr 

pub struct PointExpr {
    pub x: Expr,
    pub y: Expr,
}

A 2D point as a pair of expressions.

Fields

x: Expr

X expression.

y: Expr

Y expression.

Implementations

impl PointExpr

pub const fn new(x: Expr, y: Expr) -> Self

Point from two expressions.

pub const fn vars(x: VarId, y: VarId) -> Self

Point from two variables.

pub const fn constant(x: f64, y: f64) -> Self

Constant point.

pub fn transformed(&self, m: [f64; 6]) -> Self

Apply an affine transform [a b c d e f] (SVG convention).

pub fn eval(&self, x: &[f64]) -> (f64, f64)

Evaluate.

Trait Implementations

impl Clone for PointExpr

fn clone(&self) -> PointExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PointExpr

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

Formats the value using the given formatter.

impl PartialEq for PointExpr

fn eq(&self, other: &PointExpr) -> 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.
