Implementations

impl Field

pub fn data_type(&self) -> DataType

Returns arrow data type.

pub fn extension_name(&self) -> Option<&str>

pub fn child(&self, name: &str) -> Option<&Self>

pub fn child_mut(&mut self, name: &str) -> Option<&mut Self>

Trait Implementations

impl Clone for Field

fn clone(&self) -> Field

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Field

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

Formats the value using the given formatter.

impl Display for Field

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

Formats the value using the given formatter.

impl From<&Field> for Field

fn from(field: &Field) -> Self

Converts to this type from the input type.

impl From<&Field> for Field

fn from(field: &Field) -> Self

Converts to this type from the input type.

impl From<&Field> for Field

fn from(field: &Field) -> Self

Converts to this type from the input type.

impl From<&Field> for Vec<Field>

fn from(field: &Field) -> Self

Converts to this type from the input type.

impl PartialEq for Field

fn eq(&self, other: &Field) -> 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 TryFrom<&Field> for Field

type Error = Error

The type returned in the event of a conversion error.

fn try_from(field: &ArrowField) -> Result<Self>

Performs the conversion.

impl TryFrom<Field> for Field

type Error = Error

The type returned in the event of a conversion error.

fn try_from(field: ArrowField) -> Result<Self>

Performs the conversion.
