SyncPrefetchDataset

alimentar::async_prefetch

Struct SyncPrefetchDataset 

Source 
pub struct SyncPrefetchDataset { /* private fields */ }
Expand description

Synchronous wrapper for async prefetch that works with DataLoader.

This allows using async prefetch with the existing synchronous DataLoader API by blocking on the async operations internally.

Implementations§

Source§

impl SyncPrefetchDataset

Source

pub fn new(dataset: AsyncPrefetchDataset, runtime: Handle) -> Self

Creates a new sync wrapper around an async prefetch dataset.

§Arguments
  • dataset - The async dataset to wrap
  • runtime - Handle to the tokio runtime
Source

pub fn schema(&self) -> SchemaRef

Returns the schema.

Source

pub fn next_blocking(&mut self) -> Option<Result<RecordBatch>>

Gets the next batch, blocking if necessary.
