Trait StateRangeProviderFactory 

pub trait StateRangeProviderFactory {
    // Required method
    fn state_range_provider(
        &self,
        state_root: FixedBytes<32>,
    ) -> Result<Option<Box<dyn StateRangeProvider + Send>>, ProviderError>;
}

A type that resolves retained state roots into reusable state range views.

Required Methods

fn state_range_provider( &self, state_root: FixedBytes<32>, ) -> Result<Option<Box<dyn StateRangeProvider + Send>>, ProviderError>

Returns a view pinned to state_root, or None if that root is not retained.

Dyn Compatibility

This trait is dyn compatible.

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