Struct Prefetcher 

pub struct Prefetcher { /* private fields */ }

Speculative prefetcher that warms caches ahead of execution.

Implementations

impl Prefetcher

pub fn new(config: PrefetchConfig) -> Self

Create a new prefetcher with the given configuration and an empty call graph.

pub fn build_call_graph(&mut self, blobs: &[([u8; 32], Vec<[u8; 32]>)])

Build (or replace) the internal call graph from blob dependency data.

pub fn prefetch(&mut self, function_hash: &[u8; 32])

Enqueue the top-N likely callees for speculative prefetch.

Walks up to max_prefetch_depth levels in the call graph, collecting callees whose combined weight exceeds min_probability. Hashes are appended to the internal prefetch queue for the cache layer to consume.

pub fn get_prefetch_queue(&self) -> Vec<[u8; 32]>

Consume and return all hashes currently in the prefetch queue.

pub fn record_call(&mut self, caller: &[u8; 32], callee: &[u8; 32], count: u64)

Record an observed call from caller to callee, updating dynamic weights.

pub fn stats(&self) -> &PrefetchStats

Return a reference to the current prefetch statistics.
