Struct ListItem 

pub struct ListItem<'a> { /* private fields */ }

A pre-resolved view into a single row’s list of strings. The string array type is resolved once at construction, so subsequent element accesses use virtual dispatch rather than repeated downcasting.

Implementations

impl<'a> ListItem<'a>

pub fn new( values: &'a dyn StringArrayAccessor, offsets: Range<usize>, ) -> ListItem<'a>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn get(&self, list_index: usize) -> String

pub fn materialize(&self) -> Vec<String>

Trait Implementations

impl<'a> TypedGetData<'a, ListItem<'a>> for dyn GetData<'a> + '_

fn get_opt( &'a self, row_index: usize, field_name: &str, ) -> DeltaResult<Option<ListItem<'a>>>

fn get(&'a self, row_index: usize, field_name: &str) -> DeltaResult<T>
