Struct MockBlockDownloader

pub struct MockBlockDownloader<Block: BlockT> { /* private fields */ }

Implementations

impl<Block: BlockT> MockBlockDownloader<Block>

pub fn checkpoint(&mut self)

Validate that all current expectations for all methods have been satisfied, and discard them.

pub fn new() -> Self

Create a new mock object with no expectations.

This method will not be generated if the real struct already has a new method. However, it will be generated if the struct implements a trait with a new method. The trait’s new method can still be called like <MockX as TraitY>::new

impl<Block: BlockT> MockBlockDownloader<Block>

pub fn expect_download_blocks(&mut self) -> &mut Expectation<Block>

Create an Expectation for mocking the download_blocks method

pub fn expect_block_response_into_blocks(&mut self) -> &mut Expectation<Block>

Create an Expectation for mocking the block_response_into_blocks method

Trait Implementations

impl<Block: BlockT> BlockDownloader<Block> for MockBlockDownloader<Block>

fn download_blocks<'life0, 'async_trait>( &'life0 self, who: PeerId, request: BlockRequest<Block>, ) -> Pin<Box<dyn Future<Output = Result<Result<(Vec<u8>, ProtocolName), RequestFailure>, Canceled>> + Send + 'async_trait>>

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

Performs the protocol specific sequence to fetch the blocks from the peer. Output: if the download succeeds, the response is a Vec<u8> which is in a format specific to the protocol implementation. The block data can be extracted from this response using BlockDownloader::block_response_into_blocks.

fn block_response_into_blocks( &self, request: &BlockRequest<Block>, response: Vec<u8>, ) -> Result<Vec<BlockData<Block>>, BlockResponseError>

Parses the protocol specific response to retrieve the block data.

impl<Block: BlockT> Default for MockBlockDownloader<Block>

fn default() -> Self

Returns the “default value” for a type.
