Struct DfCmMatrix 

pub struct DfCmMatrix {
    pub name: String,
    pub axes: Vec<DfCmAxis>,
    pub cells: Vec<DfCmCell>,
}

The full DfCM matrix: a named set of axes and the cells that span them.

Fields

name: String

axes: Vec<DfCmAxis>

cells: Vec<DfCmCell>

Implementations

impl DfCmMatrix

pub fn new(name: impl Into<String>, axes: Vec<DfCmAxis>) -> Self

Create an empty matrix with the given axes.

pub fn expand_cartesian(&mut self)

Populate cells with one DfCmCell per point in the Cartesian product of all axis variants. Existing cells are replaced.

pub fn total(&self) -> usize

Total number of cells.

pub fn passing(&self) -> usize

Number of evaluated cells where DfCmCell::passes is true.

A cell whose actual_standing is still Standing::Unknown has not been evaluated yet and must not count as passing merely because its (also-default) expected_standing happens to equal it — otherwise unevaluated cells would trivially inflate pass_rate above the true coverage-weighted rate.

pub fn evaluated(&self) -> usize

Number of cells whose actual_standing is not Standing::Unknown.

pub fn coverage(&self) -> f64

Fraction of cells that have been evaluated (0.0–1.0).

pub fn pass_rate(&self) -> f64

Fraction of evaluated cells that pass (0.0–1.0). Returns 0.0 when none have been evaluated.

pub fn find_cell(&self, coords: &[&str]) -> Option<&DfCmCell>

Find a cell by its coordinate tuple.

pub fn find_cell_mut(&mut self, coords: &[&str]) -> Option<&mut DfCmCell>

Find a cell mutably by its coordinate tuple.

pub fn validate(&self) -> Vec<String>

Validate the matrix and return a list of human-readable error strings.

Checks:

• Every cell has the same number of coordinates as there are axes.
• No two cells share the same coordinate tuple.
• Every coordinate value at position i is a declared variant of axis i.

Trait Implementations
