Struct StellarDexService

pub struct StellarDexService<P, S>
where
    P: StellarProviderTrait + Send + Sync + 'static,
    S: StellarSignTrait + Signer + Send + Sync + 'static,
{ /* private fields */ }

Multi-strategy Stellar DEX service

This service maintains a list of DEX strategy implementations (one per configured strategy) and automatically selects the first one that can handle a given asset when methods are called. The routing logic is integrated directly into the service implementation.

Uses static dispatch via generics and an enum wrapper instead of dynamic dispatch.

Implementations

impl<P, S> StellarDexService<P, S>

where P: StellarProviderTrait + Send + Sync + 'static, S: StellarSignTrait + Signer + Send + Sync + 'static,

pub fn new(strategies: Vec<DexServiceWrapper<P, S>>) -> Self

Create a new multi-strategy DEX service with the given strategy implementations

Arguments

• strategies - Vector of DEX strategy implementations in priority order

Trait Implementations

impl<P, S> StellarDexServiceTrait for StellarDexService<P, S>

where P: StellarProviderTrait + Send + Sync + 'static, S: StellarSignTrait + Signer + Send + Sync + 'static,

fn supported_asset_types(&self) -> HashSet<AssetType>

Returns the asset types this DEX service can handle

fn can_handle_asset(&self, asset_id: &str) -> bool

Checks if this service can handle a specific asset
