ChangeEpoch

ChangeEpoch​

class ChangeEpoch

System transaction used to change the epoch

BCS

The BCS serialized form for this type is defined by the following ABNF:

change-epoch = u64  ; next epoch
u64  ; protocol version
u64  ; storage charge
u64  ; computation charge
u64  ; storage rebate
u64  ; non-refundable storage fee
u64  ; epoch start timestamp
(vector system-package)

init(epoch:protocolVersion:storageCharge:computationCharge:storageRebate:nonRefundableStorageFee:epochStartTimestampMs:systemPackages:)​

convenience init(epoch: UInt64, protocolVersion: UInt64, storageCharge: UInt64, computationCharge: UInt64, storageRebate: UInt64, nonRefundableStorageFee: UInt64, epochStartTimestampMs: UInt64, systemPackages: [SystemPackage])

debugDescription​

var debugDescription: String { get }

A textual representation of this instance, suitable for debugging.

Calling this property directly is discouraged. Instead, convert an instance of any type to a string by using the String(reflecting:) initializer. This initializer works with any type, and uses the custom debugDescription property for types that conform to CustomDebugStringConvertible:

struct Point: CustomDebugStringConvertible {
    let x: Int, y: Int

    var debugDescription: String {
        return "(\(x), \(y))"
    }
}

let p = Point(x: 21, y: 30)
let s = String(reflecting: p)
print(s)
// Prints "(21, 30)"

The conversion of p to a string in the assignment to s uses the Point type's debugDescription property.

computationCharge()​

func computationCharge() -> UInt64

The total amount of gas charged for computation during the epoch.

epoch()​

func epoch() -> UInt64

The next (to become) epoch ID.

epochStartTimestampMs()​

func epochStartTimestampMs() -> UInt64

Unix timestamp when epoch started

nonRefundableStorageFee()​

func nonRefundableStorageFee() -> UInt64

The non-refundable storage fee.

protocolVersion()​

func protocolVersion() -> UInt64

The protocol version in effect in the new epoch.

storageCharge()​

func storageCharge() -> UInt64

The total amount of gas charged for storage during the epoch.

storageRebate()​

func storageRebate() -> UInt64

The amount of storage rebate refunded to the txn senders.

systemPackages()​

func systemPackages() -> [SystemPackage]

System packages (specifically framework and move stdlib) that are written before the new epoch starts.

!=(_:_:)​

static func != (lhs: Self, rhs: Self) -> Bool

Returns a Boolean value indicating whether two values are not equal.

Inequality is the inverse of equality. For any values a and b, a != b implies that a == b is false.

This is the default implementation of the not-equal-to operator (!=) for any type that conforms to Equatable.

  • Parameters:
    • lhs: A value to compare.
    • rhs: Another value to compare.

==(_:_:)​

static func == (self: ChangeEpoch, other: ChangeEpoch) -> Bool

Returns a Boolean value indicating whether two values are equal.

Equality is the inverse of inequality. For any values a and b, a == b implies that a != b is false.

  • Parameters:
    • lhs: A value to compare.
    • rhs: Another value to compare.
