Struct InMemoryStateStore 

pub struct InMemoryStateStore { /* private fields */ }

An in-memory StateStore — the test store, and the default when no persistence is wanted (a pause+resume within one process still works; a crash loses it). Thread-safe.

Implementations

impl InMemoryStateStore

pub fn new() -> Self

A new, empty in-memory state store.

Trait Implementations

impl Debug for InMemoryStateStore

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for InMemoryStateStore

fn default() -> InMemoryStateStore

Returns the “default value” for a type.

impl StateStore for InMemoryStateStore

fn load<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<DownloadState>, DownloadError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Load the persisted state for key, or None if there is no checkpoint yet.

fn save<'life0, 'life1, 'async_trait>( &'life0 self, state: &'life1 DownloadState, ) -> Pin<Box<dyn Future<Output = Result<(), DownloadError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Persist state (overwriting any prior checkpoint for its key).

fn clear<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<(), DownloadError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Delete the checkpoint for key (called after a successful, finalized download).

fn record_bad_descriptor<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, target_key: &'life1 str, peer_id: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<(), DownloadError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Remember that peer_id supplied a descriptor for target_key that failed a final integrity gate, so a later call — or a later PROCESS — does not pay for the same lie again.

fn bad_descriptor_peers<'life0, 'life1, 'async_trait>( &'life0 self, target_key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<String>, DownloadError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

The peers with a still-live record_bad_descriptor verdict for target_key. The default returns none (this store keeps no reputation).
