A capability a backend may have: the kind of a Requirement.

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.

EnvironmentProvisioning

Environment-level provisioning (provision:), run by a controller.

PlaybookChecks

Checks that are Ansible playbooks (run from a controller).

ExecWithoutContainer

exec checks from a position with no container of its own.

NetworkAppliances

Network appliances (docker.appliance), wired the way Docker attaches networks.

Gateways

Networks routed by a machine of the environment (a network’s gateway).

VolumesAcrossShapes

One shared volume mounted by containers and VMs alike.

VmAfterContainer

A VM that waits for a container (depends_on).

MachineAliases

Extra names for a machine (aliases), dotted ones included.

Ulimits

Per-container process limits (ulimits).

TrafficControl

Link impairment (tc), applied on the path into a network.

Ipv6

Dual-stack networks (ipv6), with addresses derived from the octets.

Ipv6Only

IPv6-only networks (ipv6.only).

Ipv6Auto

IPv6 addresses the target hands out (ipv6.addresses: auto).

Secrets

Secrets delivered as files when the machines start (machines.*.secrets).

SecretOwners

A secret file owned by a given user or group (uid, gid).

ExternalNetworks

Joining an existing network by name (external), which the target never makes.

BridgedNetworks

Bridging a network to an interface of the host (bridged).

OwnedProjectFiles

A container’s file from the project with its own owner or mode (see crate::machine_files).

ExistingHostFiles

Files written on a host that already exists.

Tpm

A virtual TPM 2.0 in a VM.

MachineProcess

A process Isoloom starts on the machine: its own command (with its cwd) or healthcheck.

OwnBoot

A VM booting its own way (vm.boot): a kernel, firmware, boot order or network boot.

ContainerGpus

GPUs for a container (gpus), from the host its runtime runs on.

ContainerDevices

The host’s devices for a container (devices).

ContainerNestedVirtualization

VMs inside a container (nested_virtualization): no backend has it.

VmGpus

GPUs for a VM (gpus): passed through, or sized in.

VmDevices

The host’s devices for a VM (devices): no backend has it.

NestedVirtualization

VMs inside a VM (nested_virtualization).

NetworkMtu

A network’s own MTU (mtu).

RateLimit

A bandwidth cap on a machine’s links (rate_limit).

PrivateDns

Names served under the environment’s private DNS zone (dns.private).

PersistentVolumes

Volumes kept past down (persistent).

ExternalVolumes

Volumes that exist already (external), mounted by name.

DataDisks

Data disks beside a machine’s own (disks).

RawDisks

Data disks left unformatted, as block devices (fs: raw).

TmpfsModes

A mode on a memory-backed mount (tmpfs[].mode).

VmMoreAddresses

Several addresses on one network for a VM (lan: [10, 11]), added by its set-up.

ContainerMoreAddresses

Several addresses on one network for a container or an existing host: no backend has it.

Implementations

impl Feature

pub const ALL: &'static [Feature]

Every feature, in the order the enum declares them.

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

Its name, in kebab case (ipv6-only, vm-gpus).

Trait Implementations

impl Clone for Feature

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Feature

impl Debug for Feature

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

Formats the value using the given formatter.

impl Eq for Feature

impl Hash for Feature

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Ord for Feature

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.
