MemoryCache

dig_urn_resolver::cache

Struct MemoryCache

pub struct MemoryCache { /* private fields */ }

Expand description

A bounded in-memory LRU of verified plaintext, keyed by content_id. Bounded by BOTH an entry count and a total-byte budget (this ends up in a wallet — no unbounded growth). Process-trusted: a hit returns without re-verification.

Implementations§

impl MemoryCache

pub fn new(max_entries: usize, max_bytes: usize) -> Self

A cache bounded to max_entries entries and max_bytes total bytes.

pub fn get(&self, id: &str) -> Option<ResolvedData>

A verified hit (bumps recency), or None.

pub fn put(&self, id: String, data: ResolvedData)

Insert verified plaintext, evicting the least-recently-used entries until both bounds hold. An entry larger than the whole byte budget is simply not cached.
