A WorkloadService is a component that is part of a workload that runs once, either to completion or for the duration of the workload lifecycle.

Implementations

impl WorkloadService

pub fn new( workload_id: impl Into<Arc<str>>, workload_name: impl Into<Arc<str>>, workload_namespace: impl Into<Arc<str>>, component: Component, linker: Linker<Ctx>, volume_mounts: Vec<(PathBuf, VolumeMount)>, local_resources: LocalResources, max_restarts: u64, ) -> Self

Create a new WorkloadService with the given workload ID, wasmtime Component, Linker, volume mounts, and instance limits.

pub fn pre_instantiate(&mut self) -> Result<CommandPre<Ctx>>
