Struct Cost 

pub struct Cost {
    pub text: String,
    pub leaves: Vec<Leaf>,
    pub loads: Vec<Load>,
    pub terms: Vec<Term>,
}

Fields

text: String

leaves: Vec<Leaf>

loads: Vec<Load>

terms: Vec<Term>

Each top-level + or - term, which the answer reports on its own.

Implementations

impl Cost

pub fn typed(&self, held: Option<&[Held]>) -> Result<(), CliError>

Every term one number: before the loads are read, held is None and a load may be anything; once read, each is what it held.

pub fn paired(&self) -> Vec<Option<usize>>

The leaf each load subtracts from or is subtracted from, where it is one.
