Enum MemoryRegion 

pub enum MemoryRegion {
    GraphStorage,
    IndexBuffers,
    ExecutionBuffers,
    SpillStaging,
}

Memory region identifiers for budget partitioning.

The buffer manager divides its budget across these regions, allowing for differentiated eviction policies and pressure tracking.

Variants

GraphStorage

Graph storage: nodes, edges, properties, adjacency lists.

IndexBuffers

Index structures: btree, hash, trie indexes.

ExecutionBuffers

Query execution: DataChunks, hash tables, sort buffers.

SpillStaging

Spill staging area for operators under memory pressure.

Implementations

impl MemoryRegion

pub const fn index(&self) -> usize

Returns the array index for this region (for per-region tracking).

pub const fn name(&self) -> &'static str

Returns a human-readable name for this region.

pub const fn all() -> [Self; 4]

Returns all memory regions.

Trait Implementations

impl Clone for MemoryRegion

fn clone(&self) -> MemoryRegion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryRegion

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

Formats the value using the given formatter.

impl Display for MemoryRegion

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

Formats the value using the given formatter.

impl Hash for MemoryRegion

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 MemoryRegion

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