Struct EventQueryFilter 

pub struct EventQueryFilter { /* private fields */ }

Event filter that sorts and limits an event’s embedded markets client-side.

Only order, ascending, and max_markets are supported. Other parameters and unsupported order fields cause an error when loading. See PolymarketGammaHttpClient::request_instruments_by_event_query for supported order fields. EventSlugFilter returns all markets from the event.

Implementations

impl EventQueryFilter

pub fn new(event_slug: impl Into<String>, params: GetGammaMarketsParams) -> Self

Creates a new EventQueryFilter for a single event slug with query params.

pub fn from_queries(queries: Vec<(String, GetGammaMarketsParams)>) -> Self

Creates a new EventQueryFilter from multiple event slug + params pairs.

Trait Implementations

impl Clone for EventQueryFilter

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EventQueryFilter

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

Formats the value using the given formatter.

impl InstrumentFilter for EventQueryFilter

fn event_queries(&self) -> Option<Vec<(String, GetGammaMarketsParams)>>

Event queries with client-side sorting and limiting of embedded markets.

fn market_slugs(&self) -> Option<Vec<String>>

Market slugs for concurrent per-slug fetching via GET /markets?slug=.

fn event_slugs(&self) -> Option<Vec<String>>

Event slugs for fetching event containers via GET /events?slug=. Each event returns multiple markets.

fn query_params(&self) -> Option<GetGammaMarketsParams>

Gamma API query params for bulk filtered fetching.

fn event_params(&self) -> Option<GetGammaEventsParams>

Gamma events API query params for fetching events with full filtering.

fn search_params(&self) -> Option<GetSearchParams>

Public search API params for text-based instrument discovery.

fn accept(&self, instrument: &InstrumentAny) -> bool

Post-fetch predicate: only instruments where this returns true are kept. Default accepts all instruments. Override to refine results after fetching.

fn accept_new_market(&self, new_market: &PolymarketNewMarket) -> bool

Pre-fetch gate for new market WS events: returns true if the market should proceed to Gamma HTTP fetch. Used when this filter is set as the dedicated new_market_filter in the data client config. Default accepts all new markets.
