Struct WktType 

pub struct WktType { /* private fields */ }

A GeoArrow WKT type.

This extension type support multiple physical data types, including DataType::Utf8, DataType::LargeUtf8, and DataType::Utf8View.

Implementations

impl WktType

pub fn new(metadata: Arc<Metadata>) -> Self

Construct a new type from parts.

pub fn with_metadata(self, metadata: Arc<Metadata>) -> Self

Change the underlying Metadata

pub fn metadata(&self) -> &Arc<Metadata>

Retrieve the underlying Metadata

Trait Implementations

impl Clone for WktType

fn clone(&self) -> WktType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WktType

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

Formats the value using the given formatter.

impl Default for WktType

fn default() -> WktType

Returns the “default value” for a type.

impl ExtensionType for WktType

const NAME: &'static str = "geoarrow.wkt"

The name identifying this extension type.

type Metadata = Arc<Metadata>

The metadata type of this extension type.

fn metadata(&self) -> &Self::Metadata

Returns a reference to the metadata of this extension type, or &() if if this extension type defines no metadata (Self::Metadata=()).

fn serialize_metadata(&self) -> Option<String>

Returns the serialized representation of the metadata of this extension type, or None if this extension type defines no metadata (Self::Metadata=()).

fn deserialize_metadata( metadata: Option<&str>, ) -> Result<Self::Metadata, ArrowError>

Deserialize the metadata of this extension type from the serialized representation of the metadata. An extension type that defines no metadata should expect None for the serialized metadata and return Ok(()).

fn supports_data_type(&self, data_type: &DataType) -> Result<(), ArrowError>

Returns Ok(()) iff the given data type is supported by this extension type.

fn try_new( data_type: &DataType, metadata: Self::Metadata, ) -> Result<Self, ArrowError>

Construct this extension type for a field with the given data type and metadata.

impl Hash for WktType

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 for WktType

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