RFC0043 defines a finite-state-machine to deploy a soft fork in multiple stages. State transitions happen during epoch if conditions are met In case of reorg, transitions can go backward. Without transition, state is inherited between epochs. All blocks of a epoch share the same state.

Variants

Defined = 0

First state that each softfork starts. The 0 epoch is by definition in this state for each deployment.

Started = 1

For epochs past the start epoch.

LockedIn = 2

For one epoch after the first epoch period with STARTED epochs of which at least threshold has the associated bit set in version.

Active = 3

For all epochs after the LOCKED_IN epoch.

Failed = 4

For one epoch period past the timeout_epoch, if LOCKED_IN was not reached.

Trait Implementations

impl Clone for ThresholdState

fn clone(&self) -> ThresholdState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ThresholdState

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

Formats the value using the given formatter.

impl From<ThresholdState> for DeploymentState

fn from(state: ThresholdState) -> Self

Converts to this type from the input type.

impl PartialEq for ThresholdState

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