Trait HashedPostStateProvider 

pub trait HashedPostStateProvider {
    // Required method
    fn hashed_post_state(
        &self,
        bundle_state: &BundleState,
    ) -> Result<HashedPostState, ProviderError>;
}

Available on crate feature storage-api only.

Trait that provides the hashed state from various sources.

Required Methods

fn hashed_post_state( &self, bundle_state: &BundleState, ) -> Result<HashedPostState, ProviderError>

Returns the HashedPostState of the provided BundleState, materializing zero-valued updates for parent storage of accounts that were destroyed but remain in the post-state.

Providers backed by an exact parent-state view also materialize terminally destroyed accounts with explicit zero-valued storage updates.

Dyn Compatibility

This trait is dyn compatible.

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