Struct VortexWriteOptions 

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

Configure a new writer, which can eventually be used to write an ArrayStream into a sink that implements VortexWrite.

Unless overridden, the default write strategy will be used with no additional configuration.

Implementations§

Source§

impl VortexWriteOptions

Source

pub fn with_handle(self, handle: Handle) -> Self

Configure a Handle for driving async tasks.

If not provided, a handle will try to be inferred from Handle::find.

Source

pub fn with_some_handle(self, handle: Option<Handle>) -> Self

See VortexWriteOptions::with_handle.

Source

pub fn with_strategy(self, strategy: Arc<dyn LayoutStrategy>) -> Self

Replace the default layout strategy with the provided one.

Source

pub fn exclude_dtype(self) -> Self

Exclude the DType from the Vortex file. You must provide the DType to the reader.

Source

pub fn with_file_statistics(self, file_statistics: Vec<Stat>) -> Self

Configure which statistics to compute at the file-level.

Source§

impl VortexWriteOptions

Source

pub fn blocking<B: BlockingRuntime + Default>(self) -> BlockingWrite<B>

Drop into the blocking writer API using the given runtime.

Source

pub fn with_blocking<B: BlockingRuntime>(self, runtime: B) -> BlockingWrite<B>

Drop into the blocking writer API using the given runtime.

Source

pub async fn write<W: VortexWrite + Unpin, S: ArrayStream + Send + 'static>( self, write: W, stream: S, ) -> VortexResult<WriteSummary>

Write an ArrayStream as a Vortex file.

Note that buffers are flushed as soon as they are available with no buffering, the caller is responsible for deciding how to configure buffering on the underlying Write sink.

Source

pub fn writer<'w, W: VortexWrite + Unpin + 'w>( self, write: W, dtype: DType, ) -> Writer<'w>

Create a push-based Writer that can be used to incrementally write arrays to the file.
