[−][src]Struct parquet::file::serialized_reader::SerializedFileReader
A serialized implementation for Parquet FileReader.
Implementations
impl<R: 'static + ChunkReader> SerializedFileReader<R>[src]
pub fn new(chunk_reader: R) -> Result<Self>[src]
Creates file reader from a Parquet file. Returns error if Parquet file does not exist or is corrupt.
