Implementations

impl DataType

pub fn value_within_range(&self, other: AnyValue<'_>) -> bool

pub fn inner_dtype(&self) -> Option<&DataType>

pub fn to_physical(&self) -> DataType

Convert to the physical data type

pub fn is_logical(&self) -> bool

Check if this DataType is a logical type

pub fn is_temporal(&self) -> bool

Check if this DataType is a temporal type

pub fn is_primitive(&self) -> bool

Check if datatype is a primitive type. By that we mean that it is not a container type.

pub fn is_numeric(&self) -> bool

Check if this DataType is a numeric type

pub fn is_float(&self) -> bool

pub fn is_integer(&self) -> bool

pub fn is_signed(&self) -> bool

pub fn is_unsigned(&self) -> bool

pub fn to_arrow(&self) -> ArrowDataType

Convert to an Arrow data type.

Trait Implementations

impl Clone for DataType

fn clone(&self) -> DataType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DataType

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

Formats the value using the given formatter.

impl Default for DataType

fn default() -> Self

Returns the “default value” for a type.

impl Display for DataType

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

Formats the value using the given formatter.

impl<'a> From<&AnyValue<'a>> for DataType

fn from(val: &AnyValue<'a>) -> Self

Converts to this type from the input type.

impl From<&DataType> for DataType

fn from(dt: &ArrowDataType) -> Self

Converts to this type from the input type.

impl From<AnyValue<'_>> for DataType

fn from(value: AnyValue<'_>) -> Self

Converts to this type from the input type.

impl Hash for DataType

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

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<DataType> for DataType

fn eq(&self, other: &Self) -> 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 PartialEq<DataType> for DataType

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