Expand description

Actors operations whose scope of action is actors other than the calling actor. The calling actor’s state may be consulted to resolve some.

Required Methods§

source

fn resolve_address(&self, address: &Address) -> Result<u64, ExecutionError>

Resolves an address of any protocol to an ID address (via the Init actor’s table). This allows resolution of externally-provided SECP, BLS, or actor addresses to the canonical form. If the argument is an ID address it is returned directly.

source

fn lookup_delegated_address( &self, actor_id: u64, ) -> Result<Option<Address>, ExecutionError>

Looks up the “delegated” (f4) address of the specified actor, if any.

source

fn get_actor_code_cid(&self, id: u64) -> Result<Cid<64>, ExecutionError>

Look up the code CID of an actor.

source

fn next_actor_address(&self) -> Result<Address, ExecutionError>

Computes an address for a new actor. The returned address is intended to uniquely refer to the actor even in the event of a chain re-org (whereas an ID-address might refer to a different actor after messages are re-ordered). Always an ActorExec address.

source

fn create_actor( &mut self, code_cid: Cid<64>, actor_id: u64, delegated_address: Option<Address>, ) -> Result<(), ExecutionError>

Creates an actor with given code_cid, actor_id, delegated_address (if specified), and an empty state.

source

fn install_actor(&mut self, code_cid: Cid<64>) -> Result<(), ExecutionError>

source

fn get_builtin_actor_type( &self, code_cid: &Cid<64>, ) -> Result<u32, ExecutionError>

Returns the actor’s “type” (if builitin) or 0 (if not).

source

fn get_code_cid_for_type(&self, typ: u32) -> Result<Cid<64>, ExecutionError>

Returns the CodeCID for the supplied built-in actor type.

source

fn balance_of(&self, actor_id: u64) -> Result<TokenAmount, ExecutionError>

Returns the balance associated with an actor id
