Struct ArrayBuilderState 

pub struct ArrayBuilderState<'a> {
    metadata_offsets: &'a mut Vec<usize>,
    value_offsets: &'a mut Vec<usize>,
    nulls: &'a mut NullBufferBuilder,
}

Builder-specific state for array building that manages array-level offsets and nulls. See [VariantBuilderExt] for details.

Fields

metadata_offsets: &'a mut Vec<usize>

value_offsets: &'a mut Vec<usize>

nulls: &'a mut NullBufferBuilder

Trait Implementations

impl BuilderSpecificState for ArrayBuilderState<'_>

fn finish( &mut self, metadata_builder: &mut dyn MetadataBuilder, value_builder: &mut ValueBuilder, )

Called by [ParentState::finish] to apply any pending builder-specific changes.

fn rollback(&mut self)

Called by [ParentState::drop] to revert any changes that were eagerly applied, if [ParentState::finish] was never invoked.

impl<'a> Debug for ArrayBuilderState<'a>

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

Formats the value using the given formatter.
