Enum Defined 

pub enum Defined {
    New(MeasureRow),
    Unchanged(u32),
    Replaced {
        row: MeasureRow,
        reshaped: bool,
    },

What define_measure found to do.

Variants

New(MeasureRow)

A new derived measure: insert the row and create its result table.

Unchanged(u32)

The measure id already has this formula: change nothing.

Replaced

A new formula for an existing derived measure: update its row, then recompute it and its dependents.

Fields

row: MeasureRow

The updated row (id, name and description kept).

reshaped: bool

Its value type or dimensions changed: recreate its result table.

Lambda

A named LAMBDA (define_lambda): insert or update its row, then recompute callers and their dependents.

Fields

row: LambdaRow

The new or updated row.

callers: Vec<MeasureId>

The derived measures that call it, directly or through other lambdas (none for a new lambda).
