Struct FillProvider

pub struct FillProvider<F, P, T, N>
where
    F: TxFiller<N>,
    P: Provider<T, N>,
    T: Transport + Clone,
    N: Network,
{ /* private fields */ }

A Provider that applies one or more TxFillers.

Fills arbitrary properties in a transaction request by composing multiple fill layers. This struct should always be the outermost layer in a provider stack, and this is enforced when using ProviderBuilder::filler to construct this layer.

Users should NOT use this struct directly. Instead, use ProviderBuilder::filler to construct and apply it to a stack.
