Implementations§

Source§

impl<R> ArrowReaderBuilder<R>

Source

pub fn file_metadata(&self) -> &FileMetadata

Source

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

Source

pub fn with_projection(self, projection: ProjectionMask) -> Self

Source

pub fn with_schema(self, schema: SchemaRef) -> Self

Source

pub fn with_file_byte_range(self, range: Range<usize>) -> Self

Specifies a range of file bytes that will read the strips offset within this range

Source

pub fn schema(&self) -> SchemaRef

Returns the currently computed schema

Unless with_schema was called, this is computed dynamically based on the current projection and the underlying file format.
