Expand description

ROFL component application.

Required Associated Constants§

source

const VERSION: Version

ROFL application version.

Provided Methods§

source

fn id() -> AppId

Identifier of the application (used for registrations).

source

fn consensus_trust_root() -> Option<TrustRoot>

Return the consensus layer trust root for this runtime; if None, consensus layer integrity verification will not be performed.

source

fn new_transaction<B>(&self, method: &str, body: B) -> Transaction
where B: Encode,

Create a new unsigned transaction.

source

fn post_registration_init<'async_trait>( self: Arc<Self>, env: Environment<Self>, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
where Self: Sized + 'async_trait,

Custom post-registration initialization. It runs before any image-specific scripts are called by the runtime so it can be used to do things like set up custom storage after successful registration.

Until this function completes, no further initialization will happen.

source

fn run<'async_trait>( self: Arc<Self>, env: Environment<Self>, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
where Self: Sized + 'async_trait,

Main application processing loop.

source

fn on_runtime_block<'async_trait>( self: Arc<Self>, env: Environment<Self>, round: u64, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
where Self: Sized + 'async_trait,

Logic that runs on each runtime block. Only one of these will run concurrently.

source

fn start(self)
where Self: Sized,

Start the application.

Object Safety§

This trait is not object safe.
