This type defines the versioned types of the engine API based on the ethereum engine API.

This includes the execution payload types and payload attributes that are used to trigger a payload job. Hence this trait is also PayloadTypes.

Implementations of this type are intended to be stateless and just define the types as associated types. This type is intended for non-ethereum chains that closely mirror the ethereum engine API spec, but may have different payload, for example opstack, but structurally equivalent otherwise (same engine API RPC endpoints for example).

Required Associated Types

type ExecutionPayloadEnvelopeV1: DeserializeOwned + Serialize + Clone + Unpin + Send + Sync + 'static

Execution Payload V1 envelope type.

type ExecutionPayloadEnvelopeV2: DeserializeOwned + Serialize + Clone + Unpin + Send + Sync + 'static

Execution Payload V2 envelope type.

type ExecutionPayloadEnvelopeV3: DeserializeOwned + Serialize + Clone + Unpin + Send + Sync + 'static

Execution Payload V3 envelope type.

type ExecutionPayloadEnvelopeV4: DeserializeOwned + Serialize + Clone + Unpin + Send + Sync + 'static

Execution Payload V4 envelope type.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
