        parameters: Parameters<'static>,

Expand description

A Delegate is a webassembly code designed to act as an agent for the user on Freenet. Delegates can:

  • Store private data on behalf of the user
  • Create, read, and modify contracts
  • Create other delegates
  • Send and receive messages from other delegates and user interfaces
  • Ask the user questions and receive answers

Example use cases:

  • A delegate stores a private key for the user, other components can ask the delegate to sign messages, it will ask the user for permission
  • A delegate monitors an inbox contract and downloads new messages when they arrive

Required Methods§

Source

fn process( parameters: Parameters<'static>, attested: Option<&'static [u8]>, message: InboundDelegateMsg<'_>, ) -> Result<Vec<OutboundDelegateMsg>, DelegateError>

Process inbound message, producing zero or more outbound messages in response. All state for the delegate must be stored using the secret mechanism.

§Arguments
  • attested: an optional identifier for the client of this function. Usually will be a ContractInstanceId.

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.
