[−][src]Trait ipld_block_builder::store::ReadonlyStore

pub trait ReadonlyStore {
    fn get(
        &'a self, 
        cid: &'a CidGeneric<Codec, Code>
    ) -> Pin<Box<dyn Future<Output = Result<Box<[u8]>, StoreError>> + 'a + Send>>;
}

Implementable by ipld storage providers.

Required methods

`fn get( &'a self, cid: &'a CidGeneric<Codec, Code> ) -> Pin<Box<dyn Future<Output = Result<Box<[u8]>, StoreError>> + 'a + Send>>`

Returns a block from the store. If the block is not in the store it fetches it from the network and pins the block. This future should be wrapped in a timeout. Dropping the future cancels the request.
