Struct Metadata 

Source 
pub struct Metadata {
    pub metrics: DataFrame,
    pub geometries: DataFrame,
    pub source_data_releases: DataFrame,
    pub data_publishers: DataFrame,
    pub countries: DataFrame,
}
Expand description

The metadata struct contains the polars DataFrames for the various different metadata tables. Can be constructed from a single CountryMetadataLoader or for all countries. It also provides the various functions for searching and getting MetricRequests from the catalogue.
