Contains a variant per dispatchable extrinsic that this pallet has.

Variants

buy_ticket

Buy a ticket to enter the lottery.

This extrinsic acts as a passthrough function for call. In all situations where call alone would succeed, this extrinsic should succeed.

If call is successful, then we will attempt to purchase a ticket, which may fail silently. To detect success of a ticket purchase, you should listen for the TicketBought event.

This extrinsic must be called by a signed origin.

Fields

call: Box<<T as Config>::RuntimeCall>

set_calls

Set calls in storage which can be used to purchase a lottery ticket.

This function only matters if you use the ValidateCall implementation provided by this pallet, which uses storage to determine the valid calls.

This extrinsic must be called by the Manager origin.

Fields

calls: Vec<<T as Config>::RuntimeCall>

start_lottery

Start a lottery using the provided configuration.

This extrinsic must be called by the ManagerOrigin.

Parameters:

• price: The cost of a single ticket.
• length: How long the lottery should run for starting at the current block.
• delay: How long after the lottery end we should wait before picking a winner.
• repeat: If the lottery should repeat when completed.

Fields

price: <<T as Config>::Currency as Currency<<T as Config>::AccountId>>::Balance

length: BlockNumberFor<T>

delay: BlockNumberFor<T>

repeat: bool

stop_repeat

If a lottery is repeating, you can use this to stop the repeat. The lottery will continue to run to completion.

This extrinsic must be called by the ManagerOrigin.

impl<T: Config> Clone for Call<T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Config> Debug for Call<T>

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

Formats the value using the given formatter.

impl<T: Config> Decode for Call<T>

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<Self, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

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> Encode for Call<T>

fn size_hint(&self) -> usize

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

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

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

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