Trait TokenPreProcessor 

pub trait TokenPreProcessor: Send + Sync {
    // Required method
    fn get_tokens<'life0, 'async_trait>(
        &'life0 self,
        addresses: Vec<Bytes>,
        token_finder: Arc<dyn TokenOwnerFinding>,
        block: BlockTag,
    ) -> Pin<Box<dyn Future<Output = Vec<Token>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

Trait for retrieving additional information about tokens, such as the number of decimals and the token symbol, to help construct CurrencyToken objects.

Required Methods

fn get_tokens<'life0, 'async_trait>( &'life0 self, addresses: Vec<Bytes>, token_finder: Arc<dyn TokenOwnerFinding>, block: BlockTag, ) -> Pin<Box<dyn Future<Output = Vec<Token>> + Send + 'async_trait>>

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

Given a list of token addresses, this function retrieves additional metadata for each token.

Parameters

• addresses - A vector of token addresses to process.
• token_finder - A reference to a TokenOwnerFinding implementation to help find token owners.
• block - The block tag at which the information should be retrieved.

Returns

A vector of CurrencyToken objects, each containing the processed information for the token.

Dyn Compatibility

This trait is dyn compatible.

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