Implementations

impl<'a> UnshredVariantRowBuilder<'a>

fn null(nulls: Option<&'a NullBuffer>) -> Self

Creates an all-null row builder.

fn append_row( &mut self, builder: &mut impl VariantBuilderExt, metadata: &VariantMetadata<'_>, index: usize, ) -> Result<()>

Appends a single row at the given value index to the supplied builder.

fn try_new_opt( shredding_state: BorrowedShreddingState<'a>, ) -> Result<Option<Self>>

Creates a new UnshredVariantRowBuilder from shredding state Returns None for None/None case - caller decides how to handle based on context
