Fields

batch_size: usize

The number of FASTQ records to read at a time.

file_schema: SchemaRef

The schema of the FASTQ file.

object_store: Arc<dyn ObjectStore>

The object store to use for reading FASTQ files.

projection: Option<Vec<usize>>

Implementations

impl FASTQConfig

pub fn new(object_store: Arc<dyn ObjectStore>) -> Self

Create a new FASTQ configuration.

pub fn with_batch_size(self, batch_size: usize) -> Self

Set the batch size.

pub fn projection(&self) -> Vec<usize>

Get the projection, returning the identity projection if none is set.

pub fn projected_schema(&self) -> Result<SchemaRef>

Get the projected schema.

pub fn with_projection(self, projection: Vec<usize>) -> Self
