Struct VerifiedCache 

pub struct VerifiedCache { /* private fields */ }

LRU cache for verified XorName values.

This cache stores XorName values that have been verified to exist on the autonomi network, avoiding repeated network queries for the same data.

Each entry records which fresh proof verification level inserted it. A paid-list entry must not satisfy a later client-PUT fast-path because paid-list admission does not authorize storing the actual chunk. Stronger entries satisfy weaker lookups.

Implementations

impl VerifiedCache

pub fn new() -> Self

Create a new cache with default capacity.

pub fn with_capacity(capacity: usize) -> Self

Create a new cache with the specified capacity.

If capacity is 0, defaults to 1.

pub fn contains(&self, xorname: &XorName) -> bool

Check if a XorName is in the cache (verified under any fresh check set).

Returns true if the XorName is cached (verified to exist on autonomi). Paid-list and client-PUT lookups must use their stricter helpers.

pub fn contains_paid_list_verified(&self, xorname: &XorName) -> bool

Check if a XorName is cached AND its verification ran at least the paid-list admission check set.

A client-PUT entry returns true here because it passed the stricter store-admission path at the caller.

pub fn contains_client_put_verified(&self, xorname: &XorName) -> bool

Check if a XorName is cached AND its verification ran the full client-PUT store-admission check set.

Paid-list entries return false here because they did not pass the client-PUT store-admission path.

pub fn insert(&self, xorname: XorName)

Add a XorName verified under the full client-PUT check set.

This should be called after verifying that data exists on the autonomi network. Also upgrades an existing paid-list-verified entry.

pub fn insert_paid_list_verified(&self, xorname: XorName)

Add a XorName verified under paid-list admission checks.

Never downgrades an existing client-PUT-verified entry.

pub fn stats(&self) -> CacheStats

Get current cache statistics.

pub fn len(&self) -> usize

Get the current number of entries in the cache.

pub fn is_empty(&self) -> bool

Check if the cache is empty.

pub fn clear(&self)

Clear all entries from the cache.

Trait Implementations

impl Clone for VerifiedCache

fn clone(&self) -> VerifiedCache

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for VerifiedCache

fn default() -> Self
