Struct TieredBlockCache 

pub struct TieredBlockCache { /* private fields */ }

Multi-level in-process cache with hot (L1) and warm (L2) tiers.

L1 is smaller and faster. L2 catches blocks evicted from L1.

Implementations

impl TieredBlockCache

pub fn new(l1_capacity: usize, l2_capacity: usize) -> Self

Create a new tiered cache.

• l1_capacity — capacity of the hot tier (number of blocks).
• l2_capacity — capacity of the warm tier (number of blocks).

pub fn get(&self, cid: &Cid) -> Option<Block>

Get a block — checks L1 then L2; promotes L2 hits to L1.

pub fn put(&self, block: Block)

Put a block into L1; blocks evicted from L1 cascade into L2.

pub fn remove(&self, cid: &Cid)

Remove a block from both tiers.

pub fn clear(&self)

Clear both tiers and reset counters.

pub fn stats(&self) -> TieredCacheStats

Return a statistics snapshot.
