Struct FunctionGraph 

pub struct FunctionGraph { /* private fields */ }

A deterministically sampled function/parametric curve with finite output. Callbacks must be pure; their panics propagate like other user callbacks.

Implementations

impl FunctionGraph

pub fn new( function: impl Fn(f64) -> f64 + Send + Sync + 'static, domain: Range<f64>, ) -> Self

Samples y=f(x), including both domain endpoints, with 128 default points.

pub fn parametric( function: impl Fn(f64) -> Point + Send + Sync + 'static, domain: Range<f64>, ) -> Self

Samples an explicit two-dimensional curve over the given parameter domain.

pub fn samples(self, samples: usize) -> Self

Sets 2..MAX_PATH_VERBS sample points; excessive requests fail before callbacks.

pub fn try_path(&self) -> Result<Path2D, ValidationError>

Evaluates a bounded sample list and rejects nonfinite output, never bridges gaps.

Trait Implementations

impl Clone for FunctionGraph

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionGraph

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

Formats the value using the given formatter.

impl Shape for FunctionGraph

fn path(&self) -> Path2D

Returns a checked path snapshot without f32 narrowing.

fn bounding_box(&self) -> Rect

Geometric bounds; defaults to the path’s cached curve bounds.

fn validate(&self) -> Result<(), ValidationError>

Reports retained authoring errors before measuring or drawing.

fn as_rect(&self) -> Option<Rect>

Exact rectangle equivalent, when available, for a rule-independent fast path.

fn fill(self, paint: impl Into<Paint>) -> Styled<Self>

where Self: Sized,

Adds floating fill paint, using the nonzero rule by default.

fn stroke(self, width: f64, paint: impl Into<Paint>) -> Styled<Self>

where Self: Sized,

Adds a bounded curve/path stroke without an implicit fill.
