Implementations§

Source§

impl EraEpochToken

Source

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

Instantiate a new EraMarker.

Source

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.

Source

pub fn get_current_era_marker(&self) -> &EraMarker

Return the EraMarker of the current Era.

Source

pub fn get_current_epoch(&self) -> Epoch

Return the epoch the Token has been created at

Source

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.

Source

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

Return the EraMarker for the coming Era if any.
