Enum Spacing 

pub enum Spacing {
    Step(NumericInput),
    Extent(NumericInput),
}

How far apart the instances of a pattern are: each Step from the last, or spread evenly over the Extent from the first to the last — a length, or an angle in degrees, plain or a formula of the part’s parameters. Serialized as {"step": 2.0}, {"extent": 10.0} or {"step": {"formula": "pitch"}}.

Variants

Step(NumericInput)

Extent(NumericInput)

Implementations

impl Spacing

pub fn step(step: impl Into<NumericInput>) -> Self

Each step — a number, or a formula’s text — from the last.

pub fn extent(extent: impl Into<NumericInput>) -> Self

Spread evenly over extent — a number, or a formula’s text.

pub fn value(&self) -> &NumericInput

The number it holds, whichever it is.

pub fn along(&self, count: usize, reader: &Reader<'_>) -> GeopResult<Row>

count instances in a row along a line, this spacing coming to a length as reader reads the parameters. Refuses a spacing that puts them on top of each other.

pub fn round(&self, count: usize, reader: &Reader<'_>) -> GeopResult<Row>

count instances in a row round an axis, this spacing coming to an angle in degrees as reader reads the parameters — an extent of a full turn spreading them over it, the last a step short of the first. Refuses a spacing that puts them on top of each other, or brings them round onto the first again.

pub fn fields<'a, A, T>( &self, f: &mut EditForm<'a, A, T>, key: &str, labels: [&str; 2], number: impl FnOnce(&str, &NumericInput) -> Number, set: impl Fn(&mut A, Spacing) + Clone + 'a, )

Its fields in f: which kind — keyed {key}_mode — and the number, keyed key, made by number(label, value) (see [NumericInput::number]). Switching the kind keeps the number. set puts the spacing set where the arguments keep it.
