Struct Source 

#[non_exhaustive]
pub struct Source {
    pub column: usize,
    pub name: String,
    pub negated: bool,
}

A cell of the final tableau’s objective row.

The shadow price of a constraint equals the z_j - c_j entry under the column of its slack (<=), its surplus (>=, negated) or, with Big-M, the constant part of the entry under its artificial variable (=). It is negated once more if the constraint was multiplied by -1 to make its right-hand side non-negative. The two-phase method drops the artificial columns, so for its equalities there is no such cell.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

column: usize

Column index in the final tableau.

name: String

Column name, e.g. "s2".

negated: bool

The shadow price is the negated cell.
