Struct StreamOptions 

pub struct StreamOptions { /* private fields */ }

Common bounded-stream execution options.

Implementations

impl StreamOptions

pub fn new( chunk_points: usize, memory_budget: MemoryBudget, ) -> RecordsResult<Self>

Creates options with an explicit positive chunk size and hard memory budget.

pub const fn with_prefetch_chunks(self, prefetch_chunks: usize) -> Self

Requests bounded source prefetch. Zero disables prefetch.

pub const fn with_ordering(self, ordering: StreamOrdering) -> Self

Selects the required ordering contract.

pub const fn chunk_points(&self) -> usize

Returns the requested maximum points per source chunk.

pub const fn memory_budget(&self) -> MemoryBudget

Returns the hard memory budget.

pub const fn prefetch_chunks(&self) -> usize

Returns the maximum number of prefetched chunks.

pub const fn ordering(&self) -> StreamOrdering

Returns the required ordering contract.

Trait Implementations

impl Clone for StreamOptions

fn clone(&self) -> StreamOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StreamOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for StreamOptions

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for StreamOptions

fn eq(&self, other: &StreamOptions) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
