Extends Alloy Provider trait with ERC-20 related features.

Provided Methods

fn retrieve_token<'life0, 'async_trait>( &'life0 self, address: Address, ) -> Pin<Box<dyn Future<Output = Result<Token, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: Sync + 'async_trait,

Retrieves a token by querying its ERC-20 contract.

fn get_token<'a, 'async_trait, Id, S>( &'a self, id: Id, store: &'a mut S, ) -> Pin<Box<dyn Future<Output = Result<&'a Token, Error>> + Send + 'async_trait>>

where 'a: 'async_trait, S: TokenStore<'a> + Send + 'async_trait, Id: Into<TokenId> + Send + 'async_trait, Self: Sync + 'async_trait,

Returns a token from the given store if present, otherwise retrieves it from its ERC-20 contract and update the store.

fn balance_of<'life0, 'async_trait>( &'life0 self, token: Address, address: Address, ) -> Pin<Box<dyn Future<Output = Result<BigDecimal, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: Sync + 'async_trait,

Retrieves the given address balance from the given token contract.

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.
