Struct MemoryBlockStore 

pub struct MemoryBlockStore(/* private fields */);

An in-memory block store to simulate IPFS.

IPFS is basically a glorified HashMap.

Implementations

impl MemoryBlockStore

pub fn new() -> Self

Creates a new in-memory block store.

Trait Implementations

impl BlockStore for MemoryBlockStore

async fn get_block(&self, cid: &Cid) -> Result<Bytes, BlockStoreError>

Retrieve a block from this store via its hash (Cid).

async fn put_block_keyed( &self, cid: Cid, bytes: impl Into<Bytes> + CondSend, ) -> Result<(), BlockStoreError>

Put a block of data into this blockstore. The block’s CID needs to match the CID given.

async fn has_block(&self, cid: &Cid) -> Result<bool, BlockStoreError>

Find out whether a call to get_block would return with a result or not.

fn put_block( &self, bytes: impl Into<Bytes> + CondSend, codec: u64, ) -> impl Future<Output = Result<Cid, BlockStoreError>> + CondSend

Put some bytes into the blockstore. These bytes should be encoded with the given codec.

fn create_cid(&self, bytes: &[u8], codec: u64) -> Result<Cid, BlockStoreError>

impl Clone for MemoryBlockStore

fn clone(&self) -> MemoryBlockStore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryBlockStore

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

Formats the value using the given formatter.

impl Default for MemoryBlockStore

fn default() -> MemoryBlockStore

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MemoryBlockStore

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for MemoryBlockStore

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
