Enum TaskKind 

#[non_exhaustive]
pub enum TaskKind {
    Subprocess(SubprocessSpec),
    Wasm(WasmSpec),
    Container(ContainerSpec),
    Embedded,
}

Execution backend for a task.

Variant	Backend	Routable
Subprocess	OS process (command, args)	yes
Container	OCI container image	yes
Embedded	In-process TaskRef	no
Wasm	WASI module (.wasm)	yes

Routable variants go through RunnerRouter::pick().

Also

• TaskSpec — embeds TaskKind as its execution backend.
• solti_runner::RunnerRouter — picks a runner based on kind and selector.

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.

Subprocess(SubprocessSpec)

Execute a subprocess on the host.

Wasm(WasmSpec)

Execute a WebAssembly module via a WASI-compatible runtime.

Container(ContainerSpec)

Run a task inside an OCI-compatible container.

Embedded

Built-in / code-defined task that does not require a runner.

Used only with SupervisorApi::submit_with_task(). Any attempt to submit this via submit() (which builds via runners) must be rejected.

Implementations

impl TaskKind

pub fn kind(&self) -> &'static str

Returns a short symbolic identifier for the runtime kind.

This is primarily intended for logging, metrics and routing:

• "subprocess"
• "container"
• "embedded"
• "wasm"

pub fn validate(&self) -> ModelResult<()>

Validate kind-specific constraints.

Every variant’s spec is checked here so the model is self-consistent without relying on transport-layer validators. If a new kind is added, extend this match — a missing branch is a compile error thanks to exhaustive matching.

Trait Implementations

impl Clone for TaskKind

fn clone(&self) -> TaskKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TaskKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TaskKind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TaskKind

fn eq(&self, other: &TaskKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for TaskKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for TaskKind
