Enum GcsError 

#[non_exhaustive]
pub enum GcsError {
    Io(Error),
    Json(Error),
    Hvsock(String),
    Protocol(String),
    Negotiation(String),
    Timeout,
    Closed,
}

Errors that can occur while talking to a UVM’s Guest Compute Service.

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.

Io(Error)

Underlying I/O failure on the hvsock transport (read/write/connect).

Json(Error)

JSON encode/decode failure on a GCS protocol message payload.

Hvsock(String)

Hyper-V socket (AF_HYPERV) setup or address resolution failure.

Protocol(String)

Generic protocol-layer violation — unexpected message type, bad sequence number, frame length out of range, etc.

Negotiation(String)

Capability/version negotiation with the in-guest GCS failed.

Timeout

An RPC or read/write operation exceeded its deadline.

Closed

The bridge connection has been closed (cleanly or by the peer).

Trait Implementations

impl Debug for GcsError

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

Formats the value using the given formatter.

impl Display for GcsError

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

Formats the value using the given formatter.

impl Error for GcsError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for GcsError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for GcsError

fn from(source: Error) -> Self
