Trait Implementations

impl Clone for DataTypeExpr

fn clone(&self) -> DataTypeExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataTypeExpr

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DataTypeExpr

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<DataType> for DataTypeExpr

fn from(value: DataType) -> DataTypeExpr

Converts to this type from the input type.

impl From<DataTypeExpr> for PyDataTypeExpr

fn from(expr: DataTypeExpr) -> Self

Converts to this type from the input type.

impl Hash for DataTypeExpr

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DataTypeExpr

fn eq(&self, other: &DataTypeExpr) -> 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.

impl Serialize for DataTypeExpr

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
