Enum Unshown 

pub enum Unshown {
    NotRead,
    NotApplied,
    BothWays {
        along: usize,
        across: usize,
    },
    Unexamined {
        why: String,
    },
}

Why a program does not show a matrix’s lines (MatrixLines::Unshown): the kind a consumer branches on, its text (std::fmt::Display) the reason.

Variants

NotRead

Its results are made of none of the matrix’s words.

NotApplied

It reads them but sums no product of them with other values: it does not apply the matrix.

BothWays

It applies the matrix both ways: along sums of one line’s words, across of one lane’s.

Fields

along: usize

How many sums of the words of one line there are.

across: usize

How many sums of the words of one lane across lines there are.

Unexamined

The program could not be examined for it, and why: its value graph could not be built, or the matrix’s buffer could not be found in it.

Fields

why: String

Why the program could not be examined.
