Struct MessagePolicy

pub struct MessagePolicy {
    pub blanket: BlanketMessagePolicy,
    pub restrict_chain_ids_to: Option<HashSet<ChainId>>,
    pub reject_message_bundles_without_application_ids: Option<HashSet<GenericApplicationId>>,
    pub reject_message_bundles_with_other_application_ids: Option<HashSet<GenericApplicationId>>,
}

Policies for automatically handling incoming messages.

Fields

blanket: BlanketMessagePolicy

The blanket policy applied to all messages.

restrict_chain_ids_to: Option<HashSet<ChainId>>

A collection of chains which restrict the origin of messages to be accepted. Option::None means that messages from all chains are accepted. An empty HashSet denotes that messages from no chains are accepted.

reject_message_bundles_without_application_ids: Option<HashSet<GenericApplicationId>>

A collection of applications: If Some, only bundles with at least one message by any of these applications will be accepted.

reject_message_bundles_with_other_application_ids: Option<HashSet<GenericApplicationId>>

A collection of applications: If Some, only bundles all of whose messages are by these applications will be accepted.
