Struct BEDConfig 

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

Configuration for a BED datasource.

Fields

batch_size: usize

The number of records to read at a time.

file_schema: SchemaRef

The schema of the BED file.

object_store: Arc<dyn ObjectStore>

The object store to use.

projection: Option<Vec<usize>>

Any projections to apply to the resulting batches.

n_fields: Option<usize>

The number of fields of the BED to read.

Implementations

impl BEDConfig

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

Create a new BED configuration.

pub fn with_n_fields(self, n_fields: usize) -> Self

Set the number of fields.

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 projected_schema(&self) -> ExonBEDResult<SchemaRef>

Get the projected schema.

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