pub struct MapType {
pub key_id: i32,

pub value_id: i32,
pub value_required: bool,
pub value: Box<Type>,
}Expand description
A map is a collection of key-value pairs with a key type and a value type. Both the key field and value field each have an integer id that is unique in the table schema. Map keys are required and map values can be either optional or required. Both map keys and map values may be any type, including nested types.
Fields§
§key_id: i32Key Id that is unique in table schema
key: Box<Type>Datatype of key
value_id: i32Value Id that is unique in table schema
value_required: boolIf value is optional or required
value: Box<Type>Datatype of value
