Module query 

The data grid query engine: filter → search → sort → group → summarize. Pure functions over rows, independent of the UI.

Structs

GridQuery

What the user asked the grid to show.

GridTable

The rows of a grid as it stands: the columns showing, the rows matching, in order.

GridTableColumn

A column of a GridTable.

QueryResult

The output of run_query: what the grid shows.

Enums

GridExportFormat

A file format of a grid’s Export menu.

GridTableKind

What a column holds, for a file to show it well.

ViewRow

A visible row of the grid: a group header or a data row.

Functions

check_formula

A formula read and checked against the columns, or what is wrong with it.

formula_value

What a formula comes to over these rows.

group_keys

Every group’s key under this query, as if all were open: what collapsing all of them means.

matches_filter

Does value (shown as display) pass a filter-row expression?

run_query

Runs the whole pipeline.

to_csv

Matching rows as CSV (RFC 4180), visible columns only, in display order.

to_table

Takes what the grid shows into a table for a file. A column with a format of its own goes as the text it shows, since only that format knows what it means.

to_tsv

Rows as tab-separated text, the way spreadsheets copy and paste: the shown (formatted) values of the visible columns, no header.
