Struct EraEpochToken

pub struct EraEpochToken { /* private fields */ }

This is a response from the EraReader. It contains EraMarkers read from the adapter. It can try to cast the given markers to SupportedEras.

Implementations

impl EraEpochToken

pub fn new( current_epoch: Epoch, current_era: EraMarker, next_era: Option<EraMarker>, ) -> Self

Instantiate a new EraMarker.

pub fn get_current_supported_era(&self) -> StdResult<SupportedEra>

Try to cast the current EraMarker to a SupportedEra. If it fails, that means the current Era is not supported by this version of the software.

pub fn get_current_era_marker(&self) -> &EraMarker

Return the EraMarker of the current Era.

pub fn get_current_epoch(&self) -> Epoch

Return the epoch the Token has been created at

pub fn get_next_supported_era(&self) -> StdResult<Option<SupportedEra>>

Try to cast the next EraMarker to a SupportedEra. If it fails, that means the coming Era will not be supported by this version of the software. This mechanism is used to issue a warning to the user asking for upgrade.

pub fn get_next_era_marker(&self) -> Option<&EraMarker>

Return the EraMarker for the coming Era if any.

Trait Implementations

impl Clone for EraEpochToken

fn clone(&self) -> EraEpochToken

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EraEpochToken

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

Formats the value using the given formatter.

impl PartialEq for EraEpochToken

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