Struct SpillWindowedFile 

pub struct SpillWindowedFile { /* private fields */ }

A bounded source backed by an immutable, automatically deleted spill file.

Implementations

impl SpillWindowedFile

pub fn open( artifact: SpillArtifact, record_bytes: usize, length: u64, max_window_bytes: usize, context: &ExecutionContext, ) -> Result<Self, Diagnostic>

Opens fixed-size records as one logical byte stream.

Errors

Returns a resource diagnostic if buffers, the artifact, or its record geometry are invalid.

impl SpillWindowedFile

pub const fn spill_bytes(&self) -> u64

Physical bytes retained by the execution-owned artifact.

Trait Implementations

impl Debug for SpillWindowedFile

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

Formats the value using the given formatter.

impl SourceBytes for SpillWindowedFile

fn window( &mut self, start: u64, len: usize, ) -> Result<ByteWindow<'_>, Diagnostic>

Returns at most len bytes starting at the global byte offset start.

fn len_hint(&self) -> Option<u64>

Exact source length when known without consuming the source.
