Variants

propose_spend

Fields

value: BalanceOf<T, I>

beneficiary: <<T as Config>::Lookup as StaticLookup>::Source

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)
• DbReads: ProposalCount, origin account
• DbWrites: ProposalCount, Proposals, origin account

reject_proposal

Fields

proposal_id: ProposalIndex

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

May only be called from T::RejectOrigin.

• Complexity: O(1)
• DbReads: Proposals, rejected proposer account
• DbWrites: Proposals, rejected proposer account

approve_proposal

Fields

proposal_id: ProposalIndex

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).
• DbReads: Proposals, Approvals
• DbWrite: Approvals

spend

Fields

amount: BalanceOf<T, I>

beneficiary: <<T as Config>::Lookup as StaticLookup>::Source

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.

remove_approval

Fields

proposal_id: ProposalIndex

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
• Db reads and writes: 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.

Trait Implementations

impl<T: Config<I>, I: 'static> Clone for Call<T, I>

fn clone(&self) -> Self

Returns a copy of the value.

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

Attempt to deserialise the value from input.

fn skip<I>(input: &mut I) -> Result<(), Error>where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<T: Config<I>, I: 'static> Encode for Call<T, I>

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )

Convert self to a slice and append it to the destination.

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode(&self) -> Vec<u8, Global>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<T: Config<I>, I: 'static> GetCallName for Call<T, I>

fn get_call_name(&self) -> &'static str

Return the function name of the Call.

fn get_call_names() -> &'static [&'static str]

Return all function names.

impl<T: Config<I>, I: 'static> GetDispatchInfo for Call<T, I>

Return a DispatchInfo, containing relevant information of this dispatch.

impl<T: Config<I>, I: 'static> GetDispatchInfo for Call<T, I>

fn get_dispatch_info(&self) -> DispatchInfo

👎Deprecated: Trait has moved to frame_support::dispatch

impl<T: Config<I>, I: 'static> PartialEq<Call<T, I>> for Call<T, I>

fn eq(&self, other: &Self) -> 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.
