Struct DataMetric 

pub struct DataMetric {
    pub script_path: String,
    pub table_path: String,
    pub kind: Kind,
    pub name: String,
    pub expr: String,
    pub filter: Option<String>,
}

DataMetric : One // measure or // dimension declaration, as catalogued from the script that materializes the table. expr and filter are the author’s own SQL: a reader renders a measure as expr plus, when filter is set, a trailing FILTER (WHERE filter).

Fields

script_path: String

The declaring script, and the path reads are authorized against

table_path: String

Canonical scheme-less DuckLake path, <lake>/<schema>.<table> (schema defaults to main)

kind: Kind

name: String

expr: String

filter: Option<String>

Row predicate from a measure’s trailing where

Implementations
