Struct SpillSession 

pub struct SpillSession { /* private fields */ }

A query’s spill session: namespaced, budgeted factory of spill files. Dropping the session removes the whole per-query directory.

Implementations

pub fn cap(&self) -> u64

The per-query spill cap in bytes.

pub fn used(&self) -> u64

Live bytes currently charged to this query.

pub fn budget_remaining(&self) -> u64

Per-query budget remaining.

pub fn new_writer(&self) -> Result<SpillWriter, SpillError>
