Implementations

impl SchemaTypeMap

pub fn get_key_type(&self) -> &SchemaDataType

pub fn get_value_type(&self) -> &SchemaDataType

The type of element contained in the value of this map, represented as a string containing the name of a primitive type, a struct definition, an array definition or a map definition

pub fn get_value_contains_null(&self) -> bool

Whether the value field is allowed to contain null elements.
