Struct DiffBlockStore

pub struct DiffBlockStore<S> { /* private fields */ }

An extremely simple differencing blockstore layer. This tracks all CIDs that are created.

Implementations

impl<S> DiffBlockStore<S>

pub fn wrap(inner: S) -> Self

pub fn into_inner(self) -> S

pub fn blocks(&self) -> impl Iterator<Item = Cid> + '_

Return the CIDs of the blocks that have been written so far.

Trait Implementations

impl<S: AsyncBlockStoreRead> AsyncBlockStoreRead for DiffBlockStore<S>

async fn read_block_into( &mut self, cid: Cid, contents: &mut Vec<u8>, ) -> Result<(), Error>

Read a single block from the block store into the provided buffer.

fn read_block( &mut self, cid: Cid, ) -> impl Future<Output = Result<Vec<u8>, Error>> + Send

Read a single block from the block store.

impl<S: AsyncBlockStoreWrite> AsyncBlockStoreWrite for DiffBlockStore<S>

async fn write_block( &mut self, codec: u64, hash: u64, contents: &[u8], ) -> Result<Cid, Error>

Write a single block into the block store. This will return the block’s computed hash.
