Struct iceberg_rust::model::data_types::MapType

pub struct MapType {
    pub key_id: i32,
    pub key: Box<Type>,
    pub value_id: i32,
    pub value_required: bool,
    pub value: Box<Type>,
}

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: i32

Key Id that is unique in table schema

key: Box<Type>

Datatype of key

value_id: i32

Value Id that is unique in table schema

value_required: bool

If value is optional or required

value: Box<Type>

Datatype of value

Trait Implementations

impl Debug for MapType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MapType

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<MapType> for MapType

fn eq(&self, other: &MapType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for MapType

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.
