Struct RenderOptions 

pub struct RenderOptions {
    pub width: Option<f64>,
    pub height: Option<f64>,
    pub params: Option<ParamValues>,
}

Render-time knobs for the chartml 5.0 pipeline.

Defaults preserve every legacy behavior: width / height of None fall through to the spec’s style.width / style.height, then to the renderer’s default dimensions (e.g. 800×400 for cartesian charts); params of None matches the legacy “no param overrides” path. Cloning is cheap — fields are scalar plus a small HashMap.

Fields

width: Option<f64>

Container width override in CSS pixels. None means “use the spec or the renderer’s default”.

height: Option<f64>

Container height override in CSS pixels. None means “use the spec or the renderer’s default”.

params: Option<ParamValues>

Interactive parameter values (e.g. dropdown selections) layered on top of params: defaults declared in the YAML. None skips param overrides entirely.

Implementations

impl RenderOptions

pub fn with_size(width: Option<f64>, height: Option<f64>) -> Self

Build options that only override the canvas size — no param values. Sugar for the common “I just want a different width/height” call site.

pub fn params_ref(&self) -> Option<&ParamValues>

Borrow the parameter overrides (if any). Matches the Option<&ParamValues> shape every internal callsite already uses.

Trait Implementations

impl Clone for RenderOptions

fn clone(&self) -> RenderOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RenderOptions

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

Formats the value using the given formatter.

impl Default for RenderOptions

fn default() -> RenderOptions

Returns the “default value” for a type.
