Struct Bool8

pub struct Bool8;

The extension type for 8-bit Boolean.

Extension name: arrow.bool8.

The storage type of the extension is Int8 where:

• false is denoted by the value 0.
• true can be specified using any non-zero value. Preferably 1.

Trait Implementations

impl Clone for Bool8

fn clone(&self) -> Bool8

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Bool8

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

Formats the value using the given formatter.

impl Default for Bool8

fn default() -> Bool8

Returns the “default value” for a type.

impl ExtensionType for Bool8

const NAME: &'static str = "arrow.bool8"

The name identifying this extension type.

type Metadata = &'static str

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 From<Bool8> for CanonicalExtensionType

fn from(value: Bool8) -> Self

Converts to this type from the input type.

impl PartialEq for Bool8

fn eq(&self, other: &Bool8) -> 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.
