Fields

epoch_duration_ms: Option<u64>

The duration of an epoch, in milliseconds.

stake_subsidy_start_epoch: Option<u64>

The starting epoch in which stake subsidies start being paid out

min_validator_count: Option<u64>

Minimum number of active validators at any moment.

max_validator_count: Option<u64>

Maximum number of active validators at any moment. We do not allow the number of validators in any epoch to go above this.

min_validator_joining_stake: Option<u64>

Deprecated. Lower-bound on the amount of stake required to become a validator.

validator_low_stake_threshold: Option<u64>

Deprecated. Validators with stake amount below validator_low_stake_threshold are considered to have low stake and will be escorted out of the validator set after being below this threshold for more than validator_low_stake_grace_period number of epochs.

validator_very_low_stake_threshold: Option<u64>

Deprecated. Validators with stake below validator_very_low_stake_threshold will be removed immediately at epoch change, no grace period.

validator_low_stake_grace_period: Option<u64>

A validator can have stake below validator_low_stake_threshold for this many epochs before being kicked out.

extra_fields: Option<MoveTable>

Any extra fields that are not defined statically.

Implementations

impl SystemParameters

pub fn epoch_duration_ms(&self) -> u64

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

pub fn stake_subsidy_start_epoch(&self) -> u64

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

pub fn min_validator_count(&self) -> u64

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

pub fn max_validator_count(&self) -> u64

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

pub fn min_validator_joining_stake(&self) -> u64

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

Trait Implementations

impl Clone for SystemParameters

fn clone(&self) -> SystemParameters

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SystemParameters

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

Formats the value using the given formatter.

impl Default for SystemParameters

fn default() -> Self

Returns the “default value” for a type.

impl From<SystemParametersV1> for SystemParameters

fn from(_: SystemParametersV1) -> Self

Converts to this type from the input type.

impl From<SystemParametersV2> for SystemParameters

fn from(_: SystemParametersV2) -> Self

Converts to this type from the input type.

impl Message for SystemParameters

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 SystemParameters

fn eq(&self, other: &SystemParameters) -> 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.
