Struct casperlabs_engine_storage::protocol_data::ProtocolData

pub struct ProtocolData { /* fields omitted */ }

Represents a protocol's data. Intended to be associated with a given protocol version.

Methods

impl ProtocolData

pub fn new(
    wasm_costs: WasmCosts,
    mint: URef,
    proof_of_stake: URef,
    standard_payment: URef
) -> Self

Creates a new ProtocolData value from a given WasmCosts value.

pub fn partial_with_mint(mint: URef) -> Self

Creates a new, partially-valid ProtocolData value where only the mint URef is known.

Used during commit_genesis before all system contracts' URefs are known.

pub fn partial_without_standard_payment(
    wasm_costs: WasmCosts,
    mint: URef,
    proof_of_stake: URef
) -> Self

Creates a new, partially-valid ProtocolData value where all but the standard payment uref is known.

Used during commit_genesis before all system contracts' URefs are known.

pub fn wasm_costs(&self) -> &WasmCosts

Gets the WasmCosts value from a given ProtocolData value.

pub fn mint(&self) -> URef

pub fn proof_of_stake(&self) -> URef

pub fn standard_payment(&self) -> URef

pub fn system_contracts(&self) -> Vec<URef>

Retrieves all valid system contracts stored in protocol version

Trait Implementations

impl Clone for ProtocolData

fn clone(&self) -> ProtocolData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for ProtocolData

impl Debug for ProtocolData

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

Formats the value using the given formatter.

impl Default for ProtocolData

Provides a default instance with non existing urefs and empty costs table.

Used in contexts where PoS or Mint contract is not ready yet, and pos, and mint installers are ran. For use with caution.

fn default() -> ProtocolData

Returns the "default value" for a type.

impl Eq for ProtocolData

impl FromBytes for ProtocolData

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<ProtocolData> for ProtocolData

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl StructuralEq for ProtocolData

impl StructuralPartialEq for ProtocolData

impl ToBytes for ProtocolData

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>

Consumes self and serializes to a Vec<u8>.
