Struct MultiGeomColumnSet 

pub struct MultiGeomColumnSet {
    pub table_name: String,
    pub columns: Vec<GeometryColumnDef>,
}

All geometry columns registered for a single feature table.

The first element of columns is treated as the primary geometry column (the one used by readers that only support a single geometry column per table). Additional elements are secondary columns.

Fields

table_name: String

Name of the feature table (matches gpkg_contents.table_name).

columns: Vec<GeometryColumnDef>

Ordered list of geometry columns; the first is the primary column.

Implementations

impl MultiGeomColumnSet

pub fn new(table_name: impl Into<String>) -> Self

Create a new, empty column set for table_name.

pub fn primary(&self) -> Option<&GeometryColumnDef>

Return a reference to the primary (first) geometry column, or None when no columns have been registered yet.

pub fn find_by_name(&self, column_name: &str) -> Option<&GeometryColumnDef>

Search for a geometry column by its column name.

Returns None when no column with that name exists in this set.

pub fn column_count(&self) -> usize

Return the number of registered geometry columns.

pub fn has_multiple(&self) -> bool

Return true when this table has more than one geometry column.
