pub enum MicrovmError {
    UnsupportedPlatform,
    InvalidConfig(String),
    Lifecycle(LifecycleError),
    Backend(String),
    GuestFile {
        kind: GuestFileErrorKind,

    },
    HttpProxy(HttpProxyError),
    SnapshotFormat(String),
    Io(Error),
}

Top-level error type returned by the microVM crate.

Errors are intentionally grouped by configuration, lifecycle, backend, guest file protocol, HTTP proxy, snapshot, and host I/O boundaries.

Variants

UnsupportedPlatform

KVM microVMs are not supported on the current platform or build configuration.

InvalidConfig(String)

microVM configuration is invalid.

Tuple Fields

0: String

Configuration validation failure detail.

Lifecycle(LifecycleError)

Current lifecycle state does not allow the requested operation.

Tuple Fields

0: LifecycleError

Source lifecycle-state error.

Backend(String)

KVM or guest protocol error.

Tuple Fields

0: String

Backend failure detail.

GuestFile

Guest-side file operation error.

Fields

kind: GuestFileErrorKind

Semantic category reported by the guest file protocol.

path: String

Guest path associated with the failed operation.

HttpProxy(HttpProxyError)

Controlled HTTP proxy error.

Tuple Fields

0: HttpProxyError

Source HTTP proxy error.

SnapshotFormat(String)

Snapshot format is invalid or incompatible.

Tuple Fields

0: String

Snapshot decoding or compatibility failure detail.

Io(Error)

Standard library I/O error.

Tuple Fields

0: Error

Source host I/O error.

Trait Implementations

impl Debug for MicrovmError

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

Formats the value using the given formatter.

impl Display for MicrovmError

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

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
