Struct MarketSlugFilter 

pub struct MarketSlugFilter { /* private fields */ }

Filter that provides market slugs, optionally via a dynamic closure.

Implementations

impl MarketSlugFilter

pub fn new<F: Fn() -> Vec<String> + Send + Sync + 'static>(slug_fn: F) -> Self

Creates a new MarketSlugFilter from a closure that generates slugs.

The closure is re-evaluated on each load_all() call, enabling time-based or stateful slug generation.

pub fn from_slugs(slugs: Vec<String>) -> Self

Creates a new MarketSlugFilter from a static list of market slugs.

Trait Implementations

impl Debug for MarketSlugFilter

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

Formats the value using the given formatter.

impl InstrumentFilter for MarketSlugFilter

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

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

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.
