Struct ProgramStep 

pub struct ProgramStep {
    pub id: String,
    pub operation: String,
    pub args: Value,
    pub active: Option<String>,
}

One step of a program: which operation, with which arguments, as saved, and whether it runs. The operation reads its arguments from their saved form each time it runs or is edited, so a program is plain data: it is copied for undo, compared for change, and saved as it is.

Fields

id: String

operation: String

args: Value

active: Option<String>

Whether the step runs, as a formula of the program’s parameters (crate::numeric::evaluate): it runs where the formula is not 0 — always, for none. A step that does not run is suppressed: it produces nothing, and the steps after it see the part as the steps before it left it (see crate::runner::Runner::run). "0" suppresses it outright; a column of the table a program’s configurations are looked up in, configuration.fillet, suppresses it in the configurations whose row has 0 there.

Implementations

impl ProgramStep

pub fn of<A: StepArgs>(id: impl Into<String>, args: &A) -> GeopResult<Self>

The step id of the operation args are for.

pub fn new<O: Operation>( id: impl Into<String>, args: &O::Args, ) -> GeopResult<Self>
