}Expand description
Something that should be informed about system related events.
This includes events like on_validation_data that is being
called when the parachain inherent is executed that contains the validation data.
Or like on_validation_code_applied that is called
when the new validation is written to the state. This means that
from the next block the runtime is being using this new code.
Required Methods§
Sourcefn on_validation_data(data: &PersistedValidationData)
fn on_validation_data(data: &PersistedValidationData)
Called in each blocks once when the validation data is set by the inherent.
Sourcefn on_validation_code_applied()
fn on_validation_code_applied()
Called when the validation code is being applied, aka from the next block on this is the new runtime.
Sourcefn on_relay_state_proof(relay_state_proof: &RelayChainStateProof) -> Weight
fn on_relay_state_proof(relay_state_proof: &RelayChainStateProof) -> Weight
Called to process keys from the verified relay chain state proof.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
