Struct ChangeEpoch

pub struct ChangeEpoch {
    pub epoch: Option<u64>,
    pub protocol_version: Option<u64>,
    pub storage_charge: Option<u64>,
    pub computation_charge: Option<u64>,
    pub storage_rebate: Option<u64>,
    pub non_refundable_storage_fee: Option<u64>,
    pub epoch_start_timestamp: Option<Timestamp>,
    pub system_packages: Vec<SystemPackage>,
}

System transaction used to change the epoch.

Fields

epoch: Option<u64>

The next (to become) epoch ID.

protocol_version: Option<u64>

The protocol version in effect in the new epoch.

storage_charge: Option<u64>

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

computation_charge: Option<u64>

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

storage_rebate: Option<u64>

The amount of storage rebate refunded to the txn senders.

non_refundable_storage_fee: Option<u64>

The non-refundable storage fee.

epoch_start_timestamp: Option<Timestamp>

Unix timestamp when epoch started.

system_packages: Vec<SystemPackage>

System packages (specifically framework and Move stdlib) that are written before the new epoch starts. This tracks framework upgrades on chain. When executing the ChangeEpoch txn, the validator must write out the following modules. Modules are provided with the version they will be upgraded to, their modules in serialized form (which include their package ID), and a list of their transitive dependencies.

Implementations

impl ChangeEpoch

pub fn epoch(&self) -> u64

Returns the value of epoch, or the default value if epoch is unset.

pub fn protocol_version(&self) -> u64

Returns the value of protocol_version, or the default value if protocol_version is unset.

pub fn storage_charge(&self) -> u64

Returns the value of storage_charge, or the default value if storage_charge is unset.

pub fn computation_charge(&self) -> u64

Returns the value of computation_charge, or the default value if computation_charge is unset.

pub fn storage_rebate(&self) -> u64

Returns the value of storage_rebate, or the default value if storage_rebate is unset.

pub fn non_refundable_storage_fee(&self) -> u64

Returns the value of non_refundable_storage_fee, or the default value if non_refundable_storage_fee is unset.

Trait Implementations

impl Clone for ChangeEpoch

fn clone(&self) -> ChangeEpoch

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ChangeEpoch

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

Formats the value using the given formatter.

impl Default for ChangeEpoch

fn default() -> Self

Returns the “default value” for a type.

impl From<ChangeEpoch> for ChangeEpoch

fn from(value: ChangeEpoch) -> Self

Converts to this type from the input type.

impl Message for ChangeEpoch

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for ChangeEpoch

fn eq(&self, other: &ChangeEpoch) -> 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 TryFrom<&ChangeEpoch> for ChangeEpoch

type Error = TryFromProtoError

The type returned in the event of a conversion error.

fn try_from(_: &ChangeEpoch) -> Result<Self, Self::Error>

Performs the conversion.
