Trait Implementations

impl BlockStore for InMemoryBlockStore

fn store_block<'life0, 'life1, 'async_trait>( &'life0 self, block: &'life1 Block, height: u32, ) -> Pin<Box<dyn Future<Output = Result<(), Box<dyn Error + Send + Sync>>> + Send + 'async_trait>>

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

Stores a block in persistent storage.

fn get_block<'life0, 'life1, 'async_trait>( &'life0 self, hash: &'life1 BlockHash, ) -> Pin<Box<dyn Future<Output = Result<Option<Block>, Box<dyn Error + Send + Sync>>> + Send + 'async_trait>>

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

Retrieves a block by its hash.

fn get_block_header<'life0, 'life1, 'async_trait>( &'life0 self, hash: &'life1 BlockHash, ) -> Pin<Box<dyn Future<Output = Result<Option<BlockHeader>, Box<dyn Error + Send + Sync>>> + Send + 'async_trait>>

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

Retrieves a block header by its hash.

fn has_block<'life0, 'life1, 'async_trait>( &'life0 self, hash: &'life1 BlockHash, ) -> Pin<Box<dyn Future<Output = Result<bool, Box<dyn Error + Send + Sync>>> + Send + 'async_trait>>

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

Checks if a block exists in storage.

fn get_best_block_hash<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<BlockHash, Box<dyn Error + Send + Sync>>> + Send + 'async_trait>>

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

Gets the hash of the best (most-work) block in the chain.

fn get_block_height<'life0, 'life1, 'async_trait>( &'life0 self, hash: &'life1 BlockHash, ) -> Pin<Box<dyn Future<Output = Result<Option<u32>, Box<dyn Error + Send + Sync>>> + Send + 'async_trait>>

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

Gets the height of a block.

impl Default for InMemoryBlockStore

fn default() -> Self

Returns the “default value” for a type.
