Struct datafusion_execution::memory_pool::MemoryConsumer

pub struct MemoryConsumer { /* private fields */ }

A memory consumer is a named allocation traced by a particular MemoryReservation in a MemoryPool. All allocations are registered to a particular MemoryConsumer;

For help with allocation accounting, see the proxy module.

Implementations

impl MemoryConsumer

pub fn new(name: impl Into<String>) -> Self

Create a new empty MemoryConsumer that can be grown using MemoryReservation

pub fn with_can_spill(self, can_spill: bool) -> Self

Set whether this allocation can be spilled to disk

pub fn can_spill(&self) -> bool

Returns true if this allocation can spill to disk

pub fn name(&self) -> &str

Returns the name associated with this allocation

pub fn register(self, pool: &Arc<dyn MemoryPool>) -> MemoryReservation

Registers this MemoryConsumer with the provided MemoryPool returning a MemoryReservation that can be used to grow or shrink the memory reservation

Trait Implementations

impl Clone for MemoryConsumer

fn clone(&self) -> MemoryConsumer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryConsumer

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

Formats the value using the given formatter.

impl Hash for MemoryConsumer

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MemoryConsumer

fn eq(&self, other: &MemoryConsumer) -> 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.
