Struct dock_runtime::attest::pallet::Pallet

pub struct Pallet<T>(_);

The pallet implementing the on-chain logic.

Implementations

impl<T> Pallet<T>where T: Config,

pub fn set_claim( origin: <T as Config>::Origin, attests: SetAttestationClaim<T>, signature: DidOrDidMethodKeySignature<Attester> ) -> Result<(), DispatchError>

impl<T> Pallet<T>where T: Config,

pub fn attestation<KArg>(k: KArg) -> Attestation<T>where KArg: EncodeLike<Attester>,

The priority value provides replay protection and also gives attestations a partial ordering. Signatures with lesser or equal priority to those previously posted by the same entity are not accepted by the chain.

Notice that priority is not a block-number. This is intentional as it yields some desired properties and allows some potential use-cases:

• When publishing consecutive attestations, the attester need not care at which block a a previous attestation was included. This means attestations can be made over a mono-directional channel.
• Timestamps may be used as priority when available.
• A timeline of future attestations may be constructed by encrypting multiple signatures, each with the output of a verifiable delay function. A “final” attestation may be selected by assigning it the highest priority in the batch. The “final” attestation will be acceptable by the runtime regardless of whether its predecessors were submitted.

An attestation on chain with iri set to None is semantically meaningless. Setting the iri to None is equivalent to attesting to the empty claimgraph.

When Attestations::get(did).iri == Some(dat) and dat is a valid utf-8 Iri: [did dock:attestsDocumentContents dat].

Trait Implementations

impl<T> Callable<T> for Pallet<T>where T: Config,

type Call = Call<T>

impl<T> Clone for Pallet<T>

fn clone(&self) -> Pallet<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Pallet<T>

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

Formats the value using the given formatter.

impl From<<Pallet<Runtime> as Callable<Runtime>>::Call> for Call

fn from(call: CallableCallFor<Attest, Runtime>) -> Self

Converts to this type from the input type.

impl<T> GetStorageVersion for Pallet<T>where T: Config,

fn current_storage_version() -> StorageVersion

Returns the current storage version as supported by the pallet.

fn on_chain_storage_version() -> StorageVersion

Returns the on-chain storage version of the pallet as stored in the storage.

impl<T> Hooks<<T as Config>::BlockNumber> for Pallet<T>where T: Config,

fn on_finalize(_n: BlockNumber)

The block is being finalized. Implement to have something happen.

fn on_idle(_n: BlockNumber, _remaining_weight: Weight) -> Weight

This will be run when the block is being finalized (before on_finalize). Implement to have something happen using the remaining weight. Will not fire if the remaining weight is 0. Return the weight used, the hook will subtract it from current weight used and pass the result to the next on_idle hook if it exists.

fn on_initialize(_n: BlockNumber) -> Weight

The block is being initialized. Implement to have something happen.

fn on_runtime_upgrade() -> Weight

Perform a module upgrade.

fn offchain_worker(_n: BlockNumber)

Implementing this function on a module allows you to perform long-running tasks that make (by default) validators generate transactions that feed results of those long-running computations back on chain.

fn integrity_test()

Run integrity test.

impl<T> IntegrityTest for Pallet<T>where T: Config,

fn integrity_test()

Run integrity test.

impl IsSubType<<Pallet<Runtime> as Callable<Runtime>>::Call> for Call

fn is_sub_type(&self) -> Option<&CallableCallFor<Attest, Runtime>>

Returns Some(_) if self is an instance of sub type T.

impl<T> OffchainWorker<<T as Config>::BlockNumber> for Pallet<T>where T: Config,

fn offchain_worker(n: <T as Config>::BlockNumber)

This function is being called after every block import (when fully synced).

impl<T> OnFinalize<<T as Config>::BlockNumber> for Pallet<T>where T: Config,

fn on_finalize(n: <T as Config>::BlockNumber)

The block is being finalized. Implement to have something happen.

impl<T> OnGenesis for Pallet<T>where T: Config,

fn on_genesis()

Something that should happen at genesis.

impl<T> OnIdle<<T as Config>::BlockNumber> for Pallet<T>where T: Config,

fn on_idle(n: <T as Config>::BlockNumber, remaining_weight: Weight) -> Weight

The block is being finalized. Implement to have something happen in case there is leftover weight. Check the passed remaining_weight to make sure it is high enough to allow for your pallet’s extra computation.

impl<T> OnInitialize<<T as Config>::BlockNumber> for Pallet<T>where T: Config,

fn on_initialize(n: <T as Config>::BlockNumber) -> Weight

The block is being initialized. Implement to have something happen.

impl<T> OnRuntimeUpgrade for Pallet<T>where T: Config,

fn on_runtime_upgrade() -> Weight

Perform a module upgrade.

impl<T> PalletInfoAccess for Pallet<T>where T: Config,

fn index() -> usize

Index of the pallet as configured in the runtime.

fn name() -> &'static str

Name of the pallet as configured in the runtime.

fn module_name() -> &'static str

Name of the Rust module containing the pallet.

fn crate_version() -> CrateVersion

Version of the crate containing the pallet.

impl<T> PalletsInfoAccess for Pallet<T>where T: Config,

fn count() -> usize

fn infos() -> Vec<PalletInfoData, Global>

All of the pallets’ information that this type represents.

impl<T> PartialEq<Pallet<T>> for Pallet<T>

fn eq(&self, other: &Pallet<T>) -> 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.

fn storage_info() -> Vec<StorageInfo, Global>

impl<T> Eq for Pallet<T>
