Trait PoolLocator

pub trait PoolLocator<AccountId, AssetKind, PoolId> {
    // Required methods
    fn address(id: &PoolId) -> Result<AccountId, ()>;
    fn pool_id(asset1: &AssetKind, asset2: &AssetKind) -> Result<PoolId, ()>;

    // Provided method
    fn pool_address(
        asset1: &AssetKind,
        asset2: &AssetKind,
    ) -> Result<AccountId, ()> { ... }
}

Provides means to resolve the PoolId and AccountId from a pair of assets.

Resulting PoolId remains consistent whether the asset pair is presented as (asset1, asset2) or (asset2, asset1). The derived AccountId may serve as an address for liquidity provider tokens.

Required Methods

fn address(id: &PoolId) -> Result<AccountId, ()>

Retrieves the account address associated with a valid PoolId.

fn pool_id(asset1: &AssetKind, asset2: &AssetKind) -> Result<PoolId, ()>

Identifies the PoolId for a given pair of assets.

Returns an error if the asset pair isn’t supported.

Provided Methods

fn pool_address(asset1: &AssetKind, asset2: &AssetKind) -> Result<AccountId, ()>

Retrieves the account address associated with a given asset pair.

Returns an error if the asset pair isn’t supported.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
