States derived from different contracts within a chain

Required Methods

fn table_name() -> &'static str

Table of the state as specified in StateMigrations

Provided Methods

fn create<'a, 'b, 'life0, 'life1, 'async_trait>( &'life0 self, context: &'life1 PureHandlerContext<'a, 'b>, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'a: 'async_trait, 'b: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Inserts state in the state’s table

fn read_one<'a, 'life0, 'life1, 'async_trait, C>( filters: &'life0 Filters, context: &'life1 C, ) -> Pin<Box<dyn Future<Output = Option<Self>> + Send + 'async_trait>>

where C: 'async_trait + HandlerContext<'a>, Self: 'async_trait, 'a: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Returns a single state matching filters. Panics if there are multiple.

fn read_many<'a, 'life0, 'life1, 'async_trait, C>( filters: &'life0 Filters, context: &'life1 C, ) -> Pin<Box<dyn Future<Output = Vec<Self>> + Send + 'async_trait>>

where C: 'async_trait + HandlerContext<'a>, Self: 'async_trait, 'a: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Returns states matching filters

fn update<'a, 'b, 'life0, 'life1, 'life2, 'async_trait>( &'life0 self, updates: &'life1 Updates, context: &'life2 PureHandlerContext<'a, 'b>, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'a: 'async_trait, 'b: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Updates state with the specified updates

fn delete<'a, 'b, 'life0, 'life1, 'async_trait>( &'life0 self, context: &'life1 PureHandlerContext<'a, 'b>, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'a: 'async_trait, 'b: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Deletes state from the state’s table

fn to_view(&self) -> HashMap<String, String>

fn to_complete_view<'a, 'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, table_name: &'life1 str, client: &'life2 ChaindexingRepoTxnClient<'a>, event: &'life3 Event, ) -> Pin<Box<dyn Future<Output = HashMap<String, String>> + Send + 'async_trait>>

where Self: 'async_trait, 'a: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

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.
