Arrow-independent data type definition for schema intermediate representation.

Variant names mirror Value for consistency (values ↔ types).

Implementations

impl DataTypeDef

pub fn is_primitive(&self) -> bool

pub fn type_name(&self) -> &'static str

Trait Implementations

impl Clone for DataTypeDef

fn clone(&self) -> DataTypeDef

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DataTypeDef

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

Formats the value using the given formatter.

impl PartialEq for DataTypeDef

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

Tests for self and other values to be equal, and is used by ==.

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

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