Struct RecordBatchDecoder 

Source 
pub struct RecordBatchDecoder<'a> { /* private fields */ }
Expand description

State for decoding Arrow arrays from an IPC RecordBatch structure to RecordBatch

Implementations§

Source§

impl<'a> RecordBatchDecoder<'a>

Source

pub fn with_projection(self, projection: Option<&'a [usize]>) -> Self

Set the projection (default: None)

If set, the projection is the list of column indices that will be read

Source

pub fn with_require_alignment(self, require_alignment: bool) -> Self

Set require_alignment (default: false)

If true, buffers must be aligned appropriately or error will result. If false, buffers will be copied to aligned buffers if necessary.
