Struct TempSpillFile 

pub struct TempSpillFile<S: Store> { /* private fields */ }

Owned spill file wrapper that truncates to base_len on drop.

This is used by streaming query operators that need a scratch store.

Implementations

impl<S: Store> TempSpillFile<S>

pub fn new(store: S) -> Result<Self, DbError>

pub fn append_temp_segment(&mut self, payload: &[u8]) -> Result<u64, DbError>

pub fn read_temp_payload( &mut self, offset: u64, len: u64, ) -> Result<Vec<u8>, DbError>

pub fn finish(self) -> Result<S, DbError>

Explicitly truncate away all temp spill data and return the inner store.

Trait Implementations

impl<S: Store> Drop for TempSpillFile<S>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
