Struct BAMConfig 

pub struct BAMConfig {
    pub batch_size: usize,
    pub file_schema: SchemaRef,
    pub object_store: Arc<dyn ObjectStore>,
    pub projection: Option<Vec<usize>>,
}

The configuration for the BAM data source.

Fields

batch_size: usize

The number of rows to read at a time from the object store.

file_schema: SchemaRef

The schema of the BAM file.

object_store: Arc<dyn ObjectStore>

The object store to use for reading BAM files.

projection: Option<Vec<usize>>

Any projections to apply to the resulting batches.

Implementations

impl BAMConfig

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

Create a new BAM configuration.

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

Set the batch size.

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

Set the projection.

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

Set the projection from an optional vector.

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.
