Struct Unknowns 

pub struct Unknowns(/* private fields */);

Every unknown the steps so far declared, by the state it is: gathered from their targets (Unknowns::of).

Implementations

impl Unknowns

pub fn of(reader: &Reader<'_>) -> GeopResult<Self>

The unknowns of the part reader reads: none where no step declared any, an error where a declaration failed.

Those of every instance placed in it come up behind the instance’s name, as its constraints do (see crate::Constraints::of), each starting where the instance’s part has it, if it has it at all. A state the part holds fixed stays fixed.

pub fn get(&self, state: &str) -> Option<&Unknown>

The unknown the state state is, if a step declared it.

pub fn iter(&self) -> impl Iterator<Item = &Unknown>

Every unknown, in order of their states’ names.
