Enum mexprp::Answer

pub enum Answer<N: Num> {
    Single(N),
    Multiple(Vec<N>),
}

An answer of an evaluatation. Can be either a single answer or multiple. This struct contains some helper methods for performing operations on single or multiple answers. The op method takes another Num, and a function with two Num arguments, itself and the other (as references). It performs that function on all combinations and returns an answer with all of the results in one. The unop function is similar but it performs an operation on only itself, without another value (unary operation).

Variants

Single(N)

A single answer

Multiple(Vec<N>)

Multiple answers. Will always be at least two (probably)

Methods

impl<N: Num> Answer<N>

pub fn op<F: Fn(&N, &N) -> Calculation<N>>(
    &self,
    other: &Self,
    oper: F
) -> Calculation<N>

Perform an operation on all the values of an answer with all the values of another answer

pub fn unop<F: Fn(&N) -> Calculation<N>>(&self, oper: F) -> Calculation<N>

Perform an operation on all the values of an answer

pub fn unwrap_single(self) -> N

Unwrap the single variant of an answer

pub fn to_vec(self) -> Vec<N>

Convert this answer into a vector

pub fn join(self, other: Self) -> Self

Adds all the answers of another answer to the asnwers of this answer, returning a new answer
