Struct MemoryResultCache 

pub struct MemoryResultCache { /* private fields */ }

Process-local, in-memory ResultCache.

Backed by a HashMap<String, Vec<Value>> under a std::sync::Mutex. Operations are short-lived and fully synchronous, so the mutex is never held across an .await point.

Implementations

impl MemoryResultCache

pub fn new() -> Self

Construct an empty cache.

pub fn live_handles(&self) -> usize

Number of live handles. Useful for assertions and release audits.

Trait Implementations

impl Debug for MemoryResultCache

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

Formats the value using the given formatter.

impl Default for MemoryResultCache

fn default() -> MemoryResultCache

Returns the “default value” for a type.

impl ResultCache for MemoryResultCache

fn store(&self, items: Vec<Value>) -> CachedResultHandle

Store items and return the handle the caller should publish.

fn page( &self, handle: &CachedResultHandle, offset: usize, limit: usize, ) -> Option<Vec<Value>>

Return up to limit items starting at offset. Returns None if the handle has been released or never existed; returns Some(empty) if the offset is past the end.

fn len(&self, handle: &CachedResultHandle) -> Option<usize>

Total item count for handle, or None if missing.

fn release(&self, handle: &CachedResultHandle) -> bool

Release the handle. Returns true if it existed.
