Required Methods

fn account_nonce<'life0, 'async_trait>( &'life0 self, account_id: Self::AccountId, at_block: Option<Self::Hash>, ) -> Pin<Box<dyn Future<Output = Result<Self::Index>> + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

The API to query account nonce (aka transaction index).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
