Struct DiskPlotCache 

pub struct DiskPlotCache { /* private fields */ }

Additional piece cache that exploit part of the plot that does not contain sectors yet

Trait Implementations

impl Clone for DiskPlotCache

fn clone(&self) -> DiskPlotCache

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DiskPlotCache

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

Formats the value using the given formatter.

impl PlotCache for DiskPlotCache

fn try_store_piece<'life0, 'life1, 'async_trait>( &'life0 self, piece_index: PieceIndex, piece: &'life1 Piece, ) -> Pin<Box<dyn Future<Output = Result<bool, FarmError>> + Send + 'async_trait>>

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

Store piece in cache if there is free space, and return Ok(true). Returns Ok(false) if there is no free space, or the farm or process is shutting down.

fn is_piece_maybe_stored<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 RecordKey, ) -> Pin<Box<dyn Future<Output = Result<MaybePieceStoredResult, FarmError>> + Send + 'async_trait>>

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

Check if a piece is already stored in this cache, or it can be added to this cache. The piece is not guaranteed to be stored, because it might be overwritten with a new sector any time.

fn read_piece<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 RecordKey, ) -> Pin<Box<dyn Future<Output = Result<Option<Piece>, FarmError>> + Send + 'async_trait>>

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

Read piece from cache.
