Struct ROW_ADDR_FIELD

pub struct ROW_ADDR_FIELD { /* private fields */ }

Row address field. This is nullable because its validity bitmap is sometimes used as a selection vector.

Methods from Deref<Target = ArrowField>

pub fn metadata(&self) -> &HashMap<String, String>

Returns the immutable reference to the Field’s optional custom metadata.

pub fn name(&self) -> &String

Returns an immutable reference to the Field’s name.

pub fn data_type(&self) -> &DataType

Returns an immutable reference to the Field’s DataType.

pub fn is_nullable(&self) -> bool

Indicates whether this Field supports null values.

pub fn dict_id(&self) -> Option<i64>

Returns the dictionary ID, if this is a dictionary type.

pub fn dict_is_ordered(&self) -> Option<bool>

Returns whether this Field’s dictionary is ordered, if this is a dictionary type.

pub fn contains(&self, other: &Field) -> bool

Check to see if self is a superset of other field. Superset is defined as:

• if nullability doesn’t match, self needs to be nullable
• self.metadata is a superset of other.metadata
• all other fields are equal

pub fn size(&self) -> usize

Return size of this instance in bytes.

Includes the size of Self.
