Struct InMemoryDhtStorage 

pub struct InMemoryDhtStorage { /* private fields */ }

In-memory DHT storage with LRU eviction.

When the number of items exceeds max_items, the least recently accessed item is evicted on the next put.

Implementations

impl InMemoryDhtStorage

pub fn new(max_items: usize) -> Self

Create a new in-memory storage with the given capacity limit.

Trait Implementations

impl Default for InMemoryDhtStorage

fn default() -> Self

Returns the “default value” for a type.

impl DhtStorage for InMemoryDhtStorage

fn expire(&mut self, lifetime: Duration)

M175 BUG FIX: previously used Instant::now() - lifetime, which panics when lifetime exceeds process uptime. Compare elapsed time forward via Instant::duration_since instead.

fn get_immutable(&mut self, target: &Id20) -> Option<ImmutableItem>

Retrieve an immutable item by its SHA-1 target hash.

fn put_immutable(&mut self, item: ImmutableItem) -> bool

Store an immutable item. Returns true if newly inserted, false if updated.

fn get_mutable( &mut self, public_key: &[u8; 32], salt: &[u8], ) -> Option<MutableItem>

Retrieve a mutable item by public key and salt.

fn get_mutable_by_target(&mut self, target: &Id20) -> Option<MutableItem>

Retrieve a mutable item by its SHA-1 target (i.e. SHA-1(public_key + salt)).

fn put_mutable(&mut self, item: MutableItem) -> bool

Store a mutable item. Returns true if stored (new or higher seq), false if rejected.

fn count(&self) -> (usize, usize)

Number of stored items as (immutable_count, mutable_count).
