Struct IERC20Instance

Source
pub struct IERC20Instance<T, P, N = Ethereum> {
    address: Address,
    provider: P,
    _network_transport: PhantomData<(N, T)>,
}
Expand description

A IERC20 instance.

Contains type-safe methods for interacting with an on-chain instance of the IERC20 contract located at a given address, using a given provider P.

If the contract bytecode is available (see the sol! documentation on how to provide it), the deploy and deploy_builder methods can be used to deploy a new instance of the contract.

See the module-level documentation for all the available methods.

§

fn quirk(&self, value: Quirk) -> Painted<&T>
