Struct SheetStreamReader 

pub struct SheetStreamReader<'a, R: BufRead> { /* private fields */ }

Forward-only streaming reader for worksheet XML.

Reads rows in batches without deserializing the entire worksheet into memory. The reader borrows the shared string table for resolving string cell references.

Implementations

impl<'a, R: BufRead> SheetStreamReader<'a, R>

pub fn new( source: R, sst: &'a SharedStringTable, row_limit: Option<u32>, ) -> Self

Create a new streaming reader over the given BufRead source.

sst is a reference to the shared string table for resolving shared string cell values. row_limit optionally caps the number of rows returned.

pub fn next_batch(&mut self, batch_size: usize) -> Result<Vec<StreamRow>>

Read the next batch of rows. Returns an empty Vec when there are no more rows to read.

pub fn has_more(&self) -> bool

Returns true if there are potentially more rows to read.

pub fn close(self)

Close the reader and release resources.
