Enum SpawnBackend 

#[non_exhaustive]
pub enum SpawnBackend {
    Native,
    Wasm {
        module: PathBuf,
    },
    Container {
        image: String,
    },
    Tee {
        enclave: EnclaveConfig,
    },
    Remote {
        node_id: String,
    },
}

Execution backend for spawning an agent process.

Determines how the agent’s work is executed at runtime. Only Native is implemented in K0-K2; other variants are defined to crystallize the API surface (see Symposium decisions D2, D3, C1, C8) and will return KernelError::BackendNotAvailable until their respective K-phases.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Native

Tokio task with agent_loop (K0-K2, default).

Wasm

WASM sandbox via Wasmtime (K3).

Fields

module: PathBuf

Path to the compiled WASM module.

Container

Docker/Podman container (K4).

Fields

image: String

Container image reference (e.g. “ghcr.io/org/agent:latest”).

Tee

Trusted Execution Environment – SGX, TrustZone, SEV (K6+).

Fields

enclave: EnclaveConfig

Enclave configuration.

Remote

Delegate to a remote node in the cluster (K6).

Fields

node_id: String

Cluster node identifier.
