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>
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.
actor_redirect: Vec<(Cid, Cid)>
Actor redirects for debug execution
Implementations§
source§impl NetworkConfig
impl NetworkConfig
sourcepub fn new(network_version: NetworkVersion) -> Self
pub fn new(network_version: NetworkVersion) -> Self
Create a new network config for the given network version.
sourcepub fn enable_actor_debugging(&mut self) -> &mut Self
pub fn enable_actor_debugging(&mut self) -> &mut Self
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.
sourcepub fn override_actors(&mut self, manifest: Cid) -> &mut Self
pub fn override_actors(&mut self, manifest: Cid) -> &mut Self
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).
sourcepub fn redirect_actors(&mut self, actor_redirect: Vec<(Cid, Cid)>) -> &mut Self
pub fn redirect_actors(&mut self, actor_redirect: Vec<(Cid, Cid)>) -> &mut Self
Set actor redirects for debug execution
sourcepub fn for_epoch(
&self,
epoch: ChainEpoch,
timestamp: u64,
initial_state: Cid,
) -> MachineContext
pub fn for_epoch( &self, epoch: ChainEpoch, timestamp: u64, initial_state: Cid, ) -> MachineContext
Create a [‘MachineContext’] for a given epoch, timestamp, and initial state.
