Expand description

Network-level settings. Except when testing locally, changing any of these likely requires a network upgrade.

Fields§

§network_version: NetworkVersion

The network version at epoch

§chain_id: ChainID

The Chain ID of the network.

DEFAULT: 0 (Invalid)

§max_call_depth: u32

The maximum call depth.

DEFAULT: 1024

§max_wasm_stack: u32

The maximum number of elements on wasm stack DEFAULT: 64Ki (512KiB of u64 elements)

§max_inst_memory_bytes: u64

Maximum size of memory of any Wasm instance, ie. each level of the recursion, in bytes.

DEFAULT: 512MiB

§max_memory_bytes: u64

Maximum size of memory used during the entire (recursive) message execution. This currently includes Wasm memories and table elements and will eventually be extended to include IPLD blocks and actor code.

DEFAULT: 2GiB

§max_block_size: usize

The maximum blocks size that can be created in the FVM.

DEFAULT: 1MiB

§builtin_actors_override: Option<Cid<64>>

An override for builtin-actors. If specified, this should be the CID of a builtin-actors “manifest”.

DEFAULT: None

§actor_debugging: bool

Enable actor debugging.

DEFAULT: false

§price_list: &'static PriceList

The price list.

DEFAULT: The price-list for the current network version.

Implementations§

source§

impl NetworkConfig

source

pub fn new(network_version: NetworkVersion) -> NetworkConfig

Create a new network config for the given network version.

source

pub fn enable_actor_debugging(&mut self) -> &mut NetworkConfig

Enable actor debugging. This is a consensus-critical option (affects gas usage) so it should only be enabled for local testing or as a network-wide parameter.

source

pub fn override_actors(&mut self, manifest: Cid<64>) -> &mut NetworkConfig

Override actors with the specific manifest. This is primarily useful for testing, or networks prior to NV16 (where the actor’s “manifest” isn’t specified on-chain).

source

pub fn redirect_actors( &mut self, actor_redirect: Vec<(Cid<64>, Cid<64>)>, ) -> &mut NetworkConfig

Set actor redirects for debug execution

source

pub fn for_epoch( &self, epoch: i64, timestamp: u64, initial_state: Cid<64>, ) -> MachineContext

Create a [‘MachineContext’] for a given epoch, timestamp, and initial state.

source

pub fn chain_id(&mut self, id: ChainID) -> &mut NetworkConfig

Set Chain ID of the network.
