Struct MapDataType 

pub struct MapDataType {
    pub key_type: Box<DataType>,
    pub value_type: Box<DataType>,
}

Map/Dictionary type with key-value pairs.

Supported by: ClickHouse, Snowflake (OBJECT), Databricks (MAP). PostgreSQL uses JSONB, SQL Server uses JSON string.

Example

use razeri_plugin_contract::DataType;
use razeri_plugin_contract::data_type::MapDataType;

let map = MapDataType::new(DataType::varchar(50), DataType::int());
assert_eq!(*map.key_type, DataType::varchar(50));
assert_eq!(*map.value_type, DataType::int());

Fields

key_type: Box<DataType>

The data type of map keys.

value_type: Box<DataType>

The data type of map values.

Implementations

let map = MapDataType::new(DataType::varchar(50), DataType::int());
assert_eq!(*map.key_type, DataType::varchar(50));
assert_eq!(*map.value_type, DataType::int());
