Implementations

impl<'api> CheckpointPagedQueryApi<'api>

pub fn total_supply(&self, key_0: AssetId) -> StoragePaged<CheckpointId, u128>

Total supply of the token at the checkpoint.

([AssetId], checkpointId) -> total supply at given checkpoint

pub fn balance( &self, key_0: (AssetId, CheckpointId), ) -> StoragePaged<IdentityId, u128>

Balance of a DID at a checkpoint.

([AssetId], did, checkpoint ID) -> Balance of a DID at a checkpoint

pub fn checkpoint_id_sequence(&self) -> StoragePaged<AssetId, CheckpointId>

Checkpoints ID generator sequence. ID of first checkpoint is 1 instead of 0.

([AssetId]) -> no. of checkpoints

pub fn balance_updates( &self, key_0: AssetId, ) -> StoragePaged<IdentityId, Vec<CheckpointId>>

Checkpoints where a DID’s balance was updated. ([AssetId], did) -> [checkpoint ID where user balance changed]

pub fn timestamps(&self, key_0: AssetId) -> StoragePaged<CheckpointId, u64>

Checkpoint timestamps.

Every schedule-originated checkpoint maps its ID to its due time. Every checkpoint manually created maps its ID to the time of recording.

([AssetId]) -> (checkpoint ID) -> checkpoint timestamp

pub fn schedule_id_sequence(&self) -> StoragePaged<AssetId, ScheduleId>

Checkpoint schedule ID sequence for assets.

([AssetId]) -> schedule ID

pub fn cached_next_checkpoints(&self) -> StoragePaged<AssetId, NextCheckpoints>

Cached next checkpoint for each schedule.

This is used to quickly find the next checkpoint from a asset’s schedules.

([AssetId]) -> next checkpoints

pub fn scheduled_checkpoints( &self, key_0: AssetId, ) -> StoragePaged<ScheduleId, ScheduleCheckpoints>

Scheduled checkpoints.

([AssetId], schedule ID) -> schedule checkpoints

pub fn schedule_ref_count( &self, key_0: AssetId, ) -> StoragePaged<ScheduleId, u32>

How many “strong” references are there to a given ScheduleId?

The presence of a “strong” reference, in the sense of Rc<T>, entails that the referenced schedule cannot be removed. Thus, as long as strong_ref_count(schedule_id) > 0, remove_schedule(schedule_id) will error.

([AssetId], schedule ID) -> strong ref count

pub fn schedule_points( &self, key_0: AssetId, ) -> StoragePaged<ScheduleId, Vec<CheckpointId>>

All the checkpoints a given schedule originated.

([AssetId], schedule ID) -> [checkpoint ID]

Trait Implementations

impl<'api> Clone for CheckpointPagedQueryApi<'api>

fn clone(&self) -> CheckpointPagedQueryApi<'api>

Returns a copy of the value.

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

Performs copy-assignment from source.
