Enum BackendKind 

#[non_exhaustive]
pub enum BackendKind {
    Hvf,
    Mock,
}

Identifies the concrete backend implementation reporting BackendCapabilities.

Squib ships exactly one production backend (HVF on Apple Silicon). The Mock variant exists so the trait surface can be unit-tested without a live hypervisor. The enum is #[non_exhaustive] to leave room for a future Apple replacement API without breaking downstream callers.

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.

Hvf

Apple Hypervisor.framework on Apple Silicon — squib’s only production backend.

Mock

In-process mock backend used for tests; never selectable from the CLI.

Trait Implementations

impl Clone for BackendKind

fn clone(&self) -> BackendKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BackendKind

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

Formats the value using the given formatter.

impl PartialEq for BackendKind

fn eq(&self, other: &BackendKind) -> 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.
