Struct pallet_treasury::pallet::Pallet

pub struct Pallet<T, I = ()>(_);

The Pallet struct, the main type that implements traits and standalone functions within the pallet.

Implementations

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

pub fn propose_spend( origin: OriginFor<T>, value: BalanceOf<T, I>, beneficiary: <<T as Config>::Lookup as StaticLookup>::Source ) -> DispatchResult

👎Deprecated: propose_spend will be removed in February 2024. Use spend instead.

Put forward a suggestion for spending. A deposit proportional to the value is reserved and slashed if the proposal is rejected. It is returned once the proposal is awarded.

Complexity

• O(1)

pub fn reject_proposal( origin: OriginFor<T>, proposal_id: ProposalIndex ) -> DispatchResult

👎Deprecated: reject_proposal will be removed in February 2024. Use spend instead.

Reject a proposed spend. The original deposit will be slashed.

May only be called from T::RejectOrigin.

Complexity

• O(1)

pub fn approve_proposal( origin: OriginFor<T>, proposal_id: ProposalIndex ) -> DispatchResult

👎Deprecated: approve_proposal will be removed in February 2024. Use spend instead.

Approve a proposal. At a later time, the proposal will be allocated to the beneficiary and the original deposit will be returned.

May only be called from T::ApproveOrigin.

Complexity

• O(1).

pub fn spend( origin: OriginFor<T>, amount: BalanceOf<T, I>, beneficiary: <<T as Config>::Lookup as StaticLookup>::Source ) -> DispatchResult

Propose and approve a spend of treasury funds.

• origin: Must be SpendOrigin with the Success value being at least amount.
• amount: The amount to be transferred from the treasury to the beneficiary.
• beneficiary: The destination account for the transfer.

NOTE: For record-keeping purposes, the proposer is deemed to be equivalent to the beneficiary.

pub fn remove_approval( origin: OriginFor<T>, proposal_id: ProposalIndex ) -> DispatchResult

Force a previously approved proposal to be removed from the approval queue. The original deposit will no longer be returned.

May only be called from T::RejectOrigin.

• proposal_id: The index of a proposal

Complexity

• O(A) where A is the number of approvals

Errors:

• ProposalNotApproved: The proposal_id supplied was not found in the approval queue, i.e., the proposal has not been approved. This could also mean the proposal does not exist altogether, thus there is no way it would have been approved in the first place.

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

pub fn proposal_count() -> ProposalIndex

“ Number of proposals that have been made.“

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

pub fn proposals<KArg>( k: KArg ) -> Option<Proposal<T::AccountId, BalanceOf<T, I>>>where KArg: EncodeLike<ProposalIndex>,

An auto-generated getter for Proposals.

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

pub fn approvals() -> BoundedVec<ProposalIndex, T::MaxApprovals>

An auto-generated getter for Approvals.

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

pub fn account_id() -> T::AccountId

The account ID of the treasury pot.

This actually does computation. If you need to keep using it, then make sure you cache the value and only call this once.

pub fn spend_funds() -> Weight

Spend some money! returns number of approvals before spend.

pub fn pot() -> BalanceOf<T, I>

Return the amount of money in the pot.

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”.

Run the benchmarks for this pallet.

fn on_initialize(n: BlockNumberFor<T>) -> Weight

Complexity

fn on_finalize(_n: BlockNumber)

Block finalization hook. This is called at the very end of block execution.

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

Hook to consume a block’s idle time. This will run when the block is being finalized (before Hooks::on_finalize).

fn on_runtime_upgrade() -> Weight

Hook executed when a code change (aka. a “runtime upgrade”) is detected by FRAME.

fn try_state(_n: BlockNumber) -> Result<(), DispatchError>

Execute the sanity checks of this pallet, per block.

fn pre_upgrade() -> Result<Vec<u8, Global>, DispatchError>

Execute some pre-checks prior to a runtime upgrade.

fn post_upgrade(_state: Vec<u8, Global>) -> Result<(), DispatchError>

Execute some post-checks after a runtime upgrade.

fn offchain_worker(_n: BlockNumber)

Implementing this function on a pallet allows you to perform long-running tasks that are dispatched as separate threads, and entirely independent of the main wasm runtime.

fn integrity_test()

Check the integrity of this pallet’s configuration.

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

fn on_unbalanceds<B>(amounts: impl Iterator<Item = Imbalance>)where Imbalance: Imbalance<B>,

Handler for some imbalances. The different imbalances might have different origins or meanings, dependent on the context. Will default to simply calling on_unbalanced for all of them. Infallible.
