Struct TicketSelector

Source
pub struct TicketSelector {
    pub channel_identifiers: Vec<(Hash, U256)>,
    pub index: TicketIndexSelector,
    pub win_prob: (Bound<WinningProbability>, Bound<WinningProbability>),
    pub amount: (Bound<HoprBalance>, Bound<HoprBalance>),

Expand description

Allows selecting multiple tickets (if index does not contain a single value) or a single ticket (with unitary index) in the given channel and epoch. The selection can be further restricted to select ticket only in the given state.

Fields§

§channel_identifiers: Vec<(Hash, U256)>

Channel ID and Epoch pairs.

§index: TicketIndexSelector

If given, will select ticket(s) with the given indices in the given channel and epoch. See TicketIndexSelector for possible options.

§win_prob: (Bound<WinningProbability>, Bound<WinningProbability>)

If given, the tickets are further restricted to the ones with a winning probability in this range.

§amount: (Bound<HoprBalance>, Bound<HoprBalance>)

If given, the tickets are further restricted to the ones with an amount in this range.

§state: Option<AcknowledgedTicketStatus>

Further restriction to tickets with the given state.

§only_aggregated: bool

Further restrict to only aggregated tickets.

Implementations§

Source§

impl TicketSelector

Source

pub fn new<T: Into<U256>>(channel_id: Hash, epoch: T) -> Self

Create a new ticket selector given the channel_id and epoch.

Source

pub fn also_on_channel<T: Into<U256>>(self, channel_id: Hash, epoch: T) -> Self

Allows matching tickets on multiple channels, by adding the given channel_id and epoch to the selector.

This also nullifies any prior effect of any prior calls to TicketSelector::with_index or TicketSelector::with_index_range as ticket indices cannot be matched over multiple channels.

Source

pub fn just_on_channel<T: Into<U256>>(self, channel_id: Hash, epoch: T) -> Self

Sets the selector to match only tickets on the given channel_id and epoch. This nullifies any prior calls to TicketSelector::also_on_channel.

Source

pub fn is_single_channel(&self) -> bool

Checks if this selector operates only on a single channel.

This will return false if TicketSelector::also_on_channel was called, and neither the TicketSelector::with_index nor TicketSelector::with_index_range were called subsequently.

Source

pub fn is_unique(&self) -> bool

If false is returned, the selector can fetch more than a single ticket.

Source

pub fn with_index(self, index: u64) -> Self

Returns this instance with a ticket index set. This method can be called multiple times to select multiple tickets. If TicketSelector::with_index_range was previously called, it will be replaced. If TicketSelector::also_on_channel was previously called, its effect will be nullified.

Source

pub fn with_index_range<T: RangeBounds<u64>>(self, index_bound: T) -> Self

Returns this instance with a ticket index upper bound set. If TicketSelector::with_index was previously called, it will be replaced. If TicketSelector::also_on_channel was previously called, its effect will be nullified.

Source

pub fn with_state(self, state: AcknowledgedTicketStatus) -> Self

Returns this instance with a ticket state set.

Source

pub fn with_no_state(self) -> Self

Returns this instance without a ticket state set.

Source

pub fn with_aggregated_only(self, only_aggregated: bool) -> Self

Returns this instance with only_aggregated flag value.

Source

pub fn with_winning_probability<T: RangeBounds<WinningProbability>>( self, range: T, ) -> Self

Returns this instance with a winning probability range bounds set.

Source

pub fn with_amount<T: RangeBounds<HoprBalance>>(self, range: T) -> Self

Returns this instance with the ticket amount range bounds set.
