Enum RootSource 

pub enum RootSource {
    Image(String),
    Tar(String),
    Rootfs(String),
}

The source of a workload’s root filesystem. Each variant is one concrete artifact form, matched 1:1 to the backends that accept it — modelled explicitly rather than overloading one string, because an image reference, a tar archive, and a rootfs block image are genuinely different things and a mismatch should be a typed error.

Variants

Image(String)

An OCI image reference (repo:tag or a digest) a runtime pulls from a registry; its unpacked layers become the root filesystem. Backends: docker, cloudflare. ComputeSpec::kernel does not apply.

Tar(String)

A tar rootfs archive — a blob hash in the shared store — that the node stages and unpacks into a directory to run. Backend: the native container runtime. ComputeSpec::kernel does not apply.

Rootfs(String)

A rootfs filesystem image — a blob hash in the shared store — that the node stages and attaches as the guest’s root block device. The filesystem is opaque to boatramp: the guest kernel mounts whatever it finds (ext4 by default, since compute build uses mke2fs, but any kernel-supported filesystem works). Backend: the firecracker micro-VM, which pairs it with ComputeSpec::kernel.

Implementations

impl RootSource

pub fn as_str(&self) -> &str

The underlying reference string (an image reference for RootSource::Image, a blob hash for RootSource::Tar / RootSource::Rootfs).
