Struct MemoryAwareCache 

pub struct MemoryAwareCache { /* private fields */ }

Memory-aware cache that tracks actual memory usage.

Unlike the basic cache which only tracks entry count, this estimates and enforces memory limits to prevent unbounded growth.

Implementations

impl MemoryAwareCache

pub fn new(max_size: usize) -> Self

Create a new memory-aware cache.

Arguments

• max_size - Maximum memory budget in bytes

pub fn insert( &self, key: String, value: Value, ) -> Result<(), ResourceLimitError>

Insert a value with memory tracking.

Arguments

• key - Cache key
• value - JSON value to cache

Returns

Ok(()) if inserted, Err if would exceed memory limit.

pub fn remove(&self, key: &str)

Remove an entry and update memory tracking.

Arguments

• key - Cache key to remove

pub fn current_usage(&self) -> usize

Get current memory usage in bytes.

pub fn max_size(&self) -> usize

Get maximum memory budget in bytes.

pub fn entry_count(&self) -> usize

Get the number of cached entries.

pub fn clear(&self)

Clear all entries and reset memory tracking.
