Implementations

impl VariantListHeader

const fn num_elements_size(&self) -> u32

const fn offset_size(&self) -> u32

const fn first_offset_byte(&self) -> u32

pub(crate) fn try_new(header_byte: u8) -> Result<Self, ArrowError>

Trait Implementations

impl Clone for VariantListHeader

fn clone(&self) -> VariantListHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VariantListHeader

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

Formats the value using the given formatter.

impl PartialEq for VariantListHeader

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