Fields

current_context_id: RefCell<OutgoingContextId>

block_cache: RefCell<HashMap<IncomingEndpointContextId, ScopeContext>>

a map of active request scopes for incoming blocks

incoming_sections_queue: RefCell<VecDeque<IncomingSection>>

a queue of incoming request scopes the scopes can be retrieved from the request_scopes map

section_observers: RefCell<HashMap<(IncomingContextId, IncomingSectionIndex), Box<dyn FnMut(IncomingSection)>>>

a map of observers for incoming response blocks (by context_id + block_index) contains an observer callback and an optional queue of blocks if the response block is a multi-block stream

incoming_blocks_history: RefCell<RingMap<BlockId, BlockHistoryData>>

history of all incoming blocks

Implementations

impl BlockHandler

pub fn new() -> BlockHandler

pub fn add_block_to_history( &self, block: &DXBBlock, original_socket_uuid: Option<ComInterfaceSocketUUID>, )

Adds a block to the history of incoming blocks if the block is not already in the history returns true if the block was added and not already in the history

pub fn is_block_in_history(&self, block: &DXBBlock) -> bool

Checks if a block is already in the history

pub fn get_block_data_from_history( &self, block: &DXBBlock, ) -> Option<BlockHistoryData>

pub fn handle_incoming_block(&self, block: DXBBlock)

pub fn get_new_context_id(&self) -> OutgoingContextId

pub fn register_incoming_block_observer( &self, context_id: OutgoingContextId, section_index: OutgoingSectionIndex, ) -> UnboundedReceiver<IncomingSection>

Adds a new observer for incoming blocks with a specific scope id and block index Returns a receiver that can be awaited to get the incoming sections

pub async fn wait_for_incoming_response_block( &self, context_id: OutgoingContextId, section_index: OutgoingSectionIndex, ) -> Option<IncomingSection>

Waits for incoming response block with a specific scope id and block index
