Trait StateRootStrategy 

pub trait StateRootStrategy<N, P, Evm>: Send + Sync
where
    N: NodePrimitives,
    Evm: ConfigureEvm<Primitives = N>,
{
    // Required method
    fn prepare(
        &self,
        ctx: StateRootJobContext<'_, N, P, Evm>,
    ) -> ProviderResult<PreparedStateRootJob<N>>;

    // Provided method
    fn prepare_payload_builder(
        &self,
        _ctx: PayloadStateRootJobContext<'_, N, P>,
    ) -> ProviderResult<Option<PayloadStateRootHandle>> { ... }
}

Strategy used by engine-tree validation to prepare per-block state-root work.

Required Methods

fn prepare( &self, ctx: StateRootJobContext<'_, N, P, Evm>, ) -> ProviderResult<PreparedStateRootJob<N>>

Prepares a per-block state-root job before execution starts.

A custom strategy that maintains a reusable sparse trie is responsible for consuming the pending prune request from the context when it starts the corresponding job.

Provided Methods

fn prepare_payload_builder( &self, _ctx: PayloadStateRootJobContext<'_, N, P>, ) -> ProviderResult<Option<PayloadStateRootHandle>>

Prepares the optional payload-builder state-root handle used for FCU-triggered block building.

This is consulted on every FCU that carries payload attributes. Returning None means the payload builder computes the state root itself; the stock builders fall back to a synchronous MPT state root. The default implementation returns None.

Dyn Compatibility

This trait is dyn compatible.

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