Implementations

impl Chainspec

pub fn name_hash(&self) -> ChainNameDigest

Returns the hash of the chainspec’s name.

pub fn hash(&self) -> Digest

Serializes self and hashes the resulting bytes.

pub fn try_hash(&self) -> Result<Digest, String>

Serializes self and hashes the resulting bytes, if able.

pub fn protocol_version(&self) -> ProtocolVersion

Returns the protocol version of the chainspec.

pub fn hard_reset_to_start_of_era(&self) -> Option<EraId>

Returns the era ID of where we should reset back to. This means stored blocks in that and subsequent eras are deleted from storage.

pub fn upgrade_config_from_parts( &self, pre_state_hash: Digest, current_protocol_version: ProtocolVersion, era_id: EraId, chainspec_raw_bytes: Arc<ChainspecRawBytes>, ) -> Result<ProtocolUpgradeConfig, String>

Creates an upgrade config instance from parts.

pub fn balance_holds_epoch(&self, timestamp: Timestamp) -> u64

Returns balance hold epoch based upon configured hold interval, calculated from the imputed timestamp.

pub fn is_supported(&self, lane: u8) -> bool

Is the given transaction lane supported.

pub fn get_max_serialized_length_by_category(&self, lane: u8) -> u64

Returns the max serialized for the given category.

pub fn get_max_args_length_by_category(&self, lane: u8) -> u64

Returns the max args length for the given category.

pub fn get_max_gas_limit_by_category(&self, lane: u8) -> u64

Returns the max gas limit for the given category.

pub fn get_max_transaction_count_by_category(&self, lane: u8) -> u64

Returns the max transaction count for the given category.

impl Chainspec

pub fn random(rng: &mut TestRng) -> Self

Available on crate feature testing only.

Generates a random instance using a TestRng.

pub fn with_chain_name(&mut self, chain_name: String) -> &mut Self

Available on crate feature testing only.

Set the chain name;

pub fn with_max_associated_keys( &mut self, max_associated_keys: u32, ) -> &mut Self

Available on crate feature testing only.

Set max associated keys.

pub fn with_pricing_handling( &mut self, pricing_handling: PricingHandling, ) -> &mut Self

Available on crate feature testing only.

Set pricing handling.

pub fn with_allow_prepaid(&mut self, allow_prepaid: bool) -> &mut Self

Available on crate feature testing only.

Set allow prepaid.

pub fn with_block_gas_limit(&mut self, block_gas_limit: u64) -> &mut Self

Available on crate feature testing only.

Set block gas limit.

pub fn with_vm_casper_v2(&mut self, vm_casper_v2: bool) -> &mut Self

Available on crate feature testing only.

Set vm2 casper wasm.

Trait Implementations

impl Clone for Chainspec

fn clone(&self) -> Chainspec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl DataSize for Chainspec

const IS_DYNAMIC: bool = true

If true, the type has a heap size that can vary at runtime, depending on the actual value.

const STATIC_HEAP_SIZE: usize = 0usize

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

impl Debug for Chainspec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Chainspec

fn default() -> Chainspec

Returns the “default value” for a type.

impl From<&Chainspec> for GenesisConfig

fn from(chainspec: &Chainspec) -> Self

Converts to this type from the input type.

impl FromBytes for Chainspec

fn from_bytes(bytes: &[u8]) -> Result<(Self, &[u8]), Error>

Deserializes the slice into Self.

fn from_vec(bytes: Vec<u8>) -> Result<(Self, Vec<u8>), Error>

Deserializes the Vec<u8> into Self.

impl PartialEq for Chainspec

fn eq(&self, other: &Chainspec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Chainspec

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToBytes for Chainspec

fn write_bytes(&self, writer: &mut Vec<u8>) -> Result<(), Error>

Writes &self into a mutable writer.

fn to_bytes(&self) -> Result<Vec<u8>, Error>

Serializes &self to a Vec<u8>.

fn serialized_length(&self) -> usize

Returns the length of the Vec<u8> which would be returned from a successful call to to_bytes() or into_bytes(). The data is not actually serialized, so this call is relatively cheap.

fn into_bytes(self) -> Result<Vec<u8>, Error>

where Self: Sized,

Consumes self and serializes to a Vec<u8>.
