Struct WorkloadComponent 

pub struct WorkloadComponent { /* private fields */ }

A WorkloadComponent is a component that is part of a workload.

It contains the actual Component that can be instantiated, the Linker for creating stores and instances, the available VolumeMounts to be passed as filesystem preopens, and the full list of HostPlugins that the component depends on.

Implementations

impl WorkloadComponent

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, ) -> Self

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

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

Pre-instantiate the component to prepare for instantiation.
