Trait parquet::file::reader::ChunkReader [−][src]
pub trait ChunkReader: Length { type T: Read; fn get_read(&self, start: u64, length: usize) -> Result<Self::T>; }
Expand description
The ChunkReader trait generates readers of chunks of a source. For a file system reader, each chunk might contain a clone of File bounded on a given range. For an object store reader, each read can be mapped to a range request.
