CatalogGraphSource

akar_processor::processor::graph_source

Struct CatalogGraphSource 

Source 
pub struct CatalogGraphSource { /* private fields */ }
Expand description

A GraphDataSource snapshot over the live node/rel tables of a catalog.

Implementations§

Source§

impl CatalogGraphSource

Source

pub fn new(catalog: Option<&Arc<TableCatalog>>) -> Self
