Trait ella_common::row::RowFormatView

pub trait RowFormatView<R>: Debug + IntoIterator<Item = R, IntoIter = RowViewIter<R, Self>> + Clone + 'static {
    // Required methods
    fn len(&self) -> usize;
    fn row(&self, i: usize) -> R;
    unsafe fn row_unchecked(&self, i: usize) -> R;

    // Provided methods
    fn is_empty(&self) -> bool { ... }
    fn iter(&self) -> RowViewIter<R, Self>  { ... }
}

Wrapper around Arrow data that implements typed indexing by row.

Required Methods

fn len(&self) -> usize

Returns the number of wrapped rows.

fn row(&self, i: usize) -> R

Returns the ith row.

Panics if i >= len.

unsafe fn row_unchecked(&self, i: usize) -> R

Returns the ith row without bounds checking.

Safety

Implementations must return a valid result when i < len. Calling this method where i >= len is undefined behavior.

Provided Methods

fn is_empty(&self) -> bool

Returns true if the view contains 0 rows.

fn iter(&self) -> RowViewIter<R, Self>

Returns an iterator over the rows in this view.
