Struct for each individual consensus rule change using soft fork.

Fields

bit: u8

Determines which bit in the version field of the block is to be used to signal the softfork lock-in and activation. It is chosen from the set {0,1,2,…,28}.

start: EpochNumber

Specifies the first epoch in which the bit gains meaning.

timeout: EpochNumber

Specifies an epoch at which the miner signaling ends. Once this epoch has been reached, if the softfork has not yet locked_in (excluding this epoch block’s bit state), the deployment is considered failed on all descendants of the block.

min_activation_epoch: EpochNumber

Specifies the epoch at which the softfork is allowed to become active.

period: EpochNumber

Specifies length of epochs of the signalling period.

active_mode: ActiveMode

This is useful for testing, as it means tests don’t need to deal with the activation process

threshold: Ratio

Specifies the minimum ratio of block per period, which indicate the locked_in of the softfork during the period.

Trait Implementations

impl Clone for Deployment

fn clone(&self) -> Deployment

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Deployment

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

Formats the value using the given formatter.

impl From<Deployment> for Deployment

fn from(deployment: Deployment) -> Self

Converts to this type from the input type.

impl From<Deployment> for DeploymentInfo

fn from(deployment: Deployment) -> Self

Converts to this type from the input type.

impl PartialEq for Deployment

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

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

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

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

impl Eq for Deployment

impl StructuralPartialEq for Deployment
