Struct bp_messages::target_chain::ForbidInboundMessages

Structure that may be used in place of SourceHeaderChain and MessageDispatch on chains,
where inbound messages are forbidden.
Trait Implementations§
source§impl<MessagesProof, DispatchPayload: Decode> MessageDispatch for ForbidInboundMessages<MessagesProof, DispatchPayload>
impl<MessagesProof, DispatchPayload: Decode> MessageDispatch for ForbidInboundMessages<MessagesProof, DispatchPayload>
§type DispatchPayload = DispatchPayload
type DispatchPayload = DispatchPayload
Decoded message payload type. Valid message may contain invalid payload. In this case
message is delivered, but dispatch fails. Therefore, two separate types of payload
(opaque
MessagePayload used in delivery and this DispatchPayload used in dispatch).§type DispatchLevelResult = ()
type DispatchLevelResult = ()
Fine-grained result of single message dispatch (for better diagnostic purposes)
source§fn is_active() -> bool
fn is_active() -> bool
Returns
true if dispatcher is ready to accept additional messages. The false should
be treated as a hint by both dispatcher and its consumers - i.e. dispatcher shall not
simply drop messages if it returns false. The consumer may still call the dispatch
if dispatcher has returned false. Read moresource§fn dispatch_weight(
_message: &mut DispatchMessage<Self::DispatchPayload>
) -> Weight
fn dispatch_weight( _message: &mut DispatchMessage<Self::DispatchPayload> ) -> Weight

source§fn dispatch(
_: DispatchMessage<Self::DispatchPayload>
) -> MessageDispatchResult<Self::DispatchLevelResult>
fn dispatch( _: DispatchMessage<Self::DispatchPayload> ) -> MessageDispatchResult<Self::DispatchLevelResult>
Called when inbound message is received. Read more

impl<MessagesProof: Parameter + Size, DispatchPayload> SourceHeaderChain for ForbidInboundMessages<MessagesProof, DispatchPayload>
§type MessagesProof = MessagesProof
type MessagesProof = MessagesProof
Proof that messages are sent from source chain. This may also include proof
of corresponding outbound lane states.

_proof: Self::MessagesProof,
_messages_count: u32

fn verify_messages_proof( _proof: Self::MessagesProof, _messages_count: u32 ) -> Result<ProvedMessages<Message>, VerificationError>
