Struct MatrixSpec 

pub struct MatrixSpec {
    pub dimensions: IndexMap<String, Vec<Value>>,
    pub include: Vec<MatrixCoord>,
    pub exclude: Vec<MatrixCoord>,
}

A [matrix] block, lowered into dimensions + include/exclude rows.

Fields

dimensions: IndexMap<String, Vec<Value>>

Named axes; cartesian product is over these in declaration order.

include: Vec<MatrixCoord>

include rows: extend matching combinations or append as standalone.

exclude: Vec<MatrixCoord>

exclude rows: drop any combination matching all listed keys.

Implementations

impl MatrixSpec

pub fn is_empty(&self) -> bool

true when the spec has no dimensions and no include rows. Such a spec produces zero rows and is treated as “no matrix declared” by the planner.

Trait Implementations
