Implementations

impl<T: Config<I>, I: 'static> Pallet<T, I>

pub fn propose_bounty(
    origin: OriginFor<T>,
    value: BalanceOf<T, I>,
    description: Vec<u8>
) -> DispatchResult

Propose a new bounty.

The dispatch origin for this call must be Signed.

Payment: TipReportDepositBase will be reserved from the origin account, as well as DataDepositPerByte for each byte in reason. It will be unreserved upon approval, or slashed when rejected.

• curator: The curator account whom will manage this bounty.
• fee: The curator fee.
• value: The total payment amount of this bounty, curator fee included.
• description: The description of this bounty.

pub fn approve_bounty(
    origin: OriginFor<T>,
    bounty_id: BountyIndex
) -> DispatchResult

Approve a bounty proposal. At a later time, the bounty will be funded and become active and the original deposit will be returned.

May only be called from T::ApproveOrigin.

• O(1).

pub fn propose_curator(
    origin: OriginFor<T>,
    bounty_id: BountyIndex,
    curator: <<T as Config>::Lookup as StaticLookup>::Source,
    fee: BalanceOf<T, I>
) -> DispatchResult

Assign a curator to a funded bounty.

May only be called from T::ApproveOrigin.

• O(1).

pub fn unassign_curator(
    origin: OriginFor<T>,
    bounty_id: BountyIndex
) -> DispatchResult

Unassign curator from a bounty.

This function can only be called by the RejectOrigin a signed origin.

If this function is called by the RejectOrigin, we assume that the curator is malicious or inactive. As a result, we will slash the curator when possible.

If the origin is the curator, we take this as a sign they are unable to do their job and they willingly give up. We could slash them, but for now we allow them to recover their deposit and exit without issue. (We may want to change this if it is abused.)

Finally, the origin can be anyone if and only if the curator is “inactive”. This allows anyone in the community to call out that a curator is not doing their due diligence, and we should pick a new curator. In this case the curator should also be slashed.

• O(1).

pub fn accept_curator(
    origin: OriginFor<T>,
    bounty_id: BountyIndex
) -> DispatchResult

Accept the curator role for a bounty. A deposit will be reserved from curator and refund upon successful payout.

May only be called from the curator.

• O(1).

pub fn award_bounty(
    origin: OriginFor<T>,
    bounty_id: BountyIndex,
    beneficiary: <<T as Config>::Lookup as StaticLookup>::Source
) -> DispatchResult

Award bounty to a beneficiary account. The beneficiary will be able to claim the funds after a delay.

The dispatch origin for this call must be the curator of this bounty.

• bounty_id: Bounty ID to award.
• beneficiary: The beneficiary account whom will receive the payout.

• O(1).

pub fn claim_bounty(
    origin: OriginFor<T>,
    bounty_id: BountyIndex
) -> DispatchResult

Claim the payout from an awarded bounty after payout delay.

The dispatch origin for this call must be the beneficiary of this bounty.

• bounty_id: Bounty ID to claim.

• O(1).

pub fn close_bounty(
    origin: OriginFor<T>,
    bounty_id: BountyIndex
) -> DispatchResultWithPostInfo

Cancel a proposed or active bounty. All the funds will be sent to treasury and the curator deposit will be unreserved if possible.

Only T::RejectOrigin is able to cancel a bounty.

• bounty_id: Bounty ID to cancel.

• O(1).

pub fn extend_bounty_expiry(
    origin: OriginFor<T>,
    bounty_id: BountyIndex,
    _remark: Vec<u8>
) -> DispatchResult

Extend the expiry time of an active bounty.

The dispatch origin for this call must be the curator of this bounty.

• bounty_id: Bounty ID to extend.
• remark: additional information.

• O(1).

Trait Implementations

impl<T, I: 'static> Benchmarking for Pallet<T, I>where
    T: Config + Config<I>,

fn benchmarks(extra: bool) -> Vec<BenchmarkMetadata>

Get the benchmarks available for this pallet. Generally there is one benchmark per extrinsic, so these are sometimes just called “extrinsics”.

fn run_benchmark(
    extrinsic: &[u8],
    c: &[(BenchmarkParameter, u32)],
    whitelist: &[TrackedStorageKey],
    verify: bool,
    internal_repeats: u32
) -> Result<Vec<BenchmarkResult>, BenchmarkError>

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

fn on_runtime_upgrade() -> Weight

Perform a module upgrade.

Execute some pre-checks prior to a runtime upgrade.

fn post_upgrade() -> Result<(), &'static str>

Execute some post-checks after a runtime upgrade.
