pub struct StreamReader<R: Read> { /* fields omitted */ }

Arrow Stream reader

Methods

impl<R: Read> StreamReader<R>[src]

pub fn try_new(reader: R) -> Result<Self>[src]

Try to create a new stream reader

The first message in the stream is the schema, the reader will fail if it does not encounter a schema. To check if the reader is done, use is_finished(self)

pub fn schema(&self) -> SchemaRef[src]

Return the schema of the stream

pub fn next(&mut self) -> Result<Option<RecordBatch>>[src]

Read the next record batch

pub fn is_finished(&self) -> bool[src]

Check if the stream is finished
