    // Required methods

}

Definition of a pending atomic swap action. It contains the following three phrases:

• Reserve: reserve the resources needed for a swap. This is to make sure that Claim succeeds with best efforts.
• Claim: claim any resources reserved in the first phrase.
• Cancel: cancel any resources reserved in the first phrase.

Required Methods

fn reserve( &self, source: &SourceAccountId, base_asset_id: &AssetId ) -> DispatchResult

Reserve the resources needed for the swap, from the given source. The reservation is allowed to fail. If that is the case, the the full swap creation operation is cancelled.

fn claim(&self, source: &SourceAccountId) -> bool

Claim the reserved resources, with source. Returns whether the claim succeeds.

fn weight(&self) -> Weight

Weight for executing the operation.

fn cancel(&self, source: &SourceAccountId)

Cancel the resources reserved in source.

Implementations on Foreign Types

impl<SourceAccountId, TargetAccountId, AssetId, T: Config> SwapAction<SourceAccountId, TargetAccountId, AssetId, T> for ()

Dummy implementation for cases then () used in runtime as empty SwapAction.

fn reserve( &self, _source: &SourceAccountId, _base_asset_id: &AssetId ) -> DispatchResult

fn claim(&self, _source: &SourceAccountId) -> bool

fn weight(&self) -> Weight

fn cancel(&self, _source: &SourceAccountId)
