Trait Implementations

impl Clone for QuadbinType

fn clone(&self) -> QuadbinType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QuadbinType

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

Formats the value using the given formatter.

impl Default for QuadbinType

fn default() -> QuadbinType

Returns the “default value” for a type.

impl Eq for QuadbinType

impl ExtensionType for QuadbinType

const NAME: &'static str = "rasterarrow.quadbin"

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.

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

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

fn try_new_from_field_metadata( data_type: &DataType, metadata: &HashMap<String, String>, ) -> Result<Self, ArrowError>

Construct this extension type from field metadata and data type.

impl From<QuadbinType> for DataType

fn from(value: QuadbinType) -> Self

Converts to this type from the input type.

impl Hash for QuadbinType

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 QuadbinType

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for QuadbinType

impl TryFrom<&Field> for QuadbinType

type Error = QuadbinArrowError

The type returned in the event of a conversion error.

fn try_from(field: &Field) -> QuadbinArrowResult<Self>

Performs the conversion.
