Struct TraceReader 

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

Reader for trace data from Arrow batches.

Provides efficient access to trace fields without copying data from the underlying Arrow columnar format. Each reader is bound to a specific row in the batch.

Implementations

impl<'a> TraceReader<'a>

pub fn new(batch: &'a RecordBatch, row_idx: usize) -> Result<Self>

Safely create a new reader for the given batch at row index and check that row_idx is within the bounds of the batch.

pub fn iter(batch: &'a RecordBatch) -> TraceIterator<'a>

Create an iterator over all rows in the batch.
