Struct SpillManager 

pub struct SpillManager { /* private fields */ }

Manages memory limits by spilling cold data to disk

Implementations

impl SpillManager

pub fn new(config: SpillConfig) -> Self

Create a new spill manager

pub fn register_segment(&self, name: &str, size: usize)

Register a memory segment for tracking

pub fn unregister_segment(&self, name: &str)

Unregister a segment

pub fn update_size(&self, name: &str, new_size: usize)

Update segment size

pub fn access(&self, name: &str)

Record access to a segment

pub fn needs_spill(&self) -> Option<Vec<String>>

Check if spilling is needed, return segments to spill

pub fn spill(&self, name: &str, data: &[u8]) -> Result<PathBuf, SpillError>

Spill a segment to disk

pub fn reload(&self, name: &str) -> Result<Option<Vec<u8>>, SpillError>

Reload a spilled segment from disk

pub fn is_spilled(&self, name: &str) -> bool

Check if a segment is spilled

pub fn stats(&self) -> SpillStats

Get current statistics

pub fn memory_usage(&self) -> usize

Get current memory usage

pub fn utilization(&self) -> f64

Get memory utilization (0.0-1.0)

pub fn list_segments(&self) -> Vec<(String, usize, bool)>

List all tracked segments

pub fn cleanup(&self) -> Result<()>

Clean up all spill files

Trait Implementations

impl Default for SpillManager

fn default() -> Self

Returns the “default value” for a type.

impl Drop for SpillManager

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.
