Enum SnapConnectionError 

#[non_exhaustive]
pub enum SnapConnectionError {
    SnapTokenSourceMissing,
    TunnelEstablishment(ConnectSnapTunSocketError),
    ControlPlaneClientCreation(CrpcClientCreationError),
    DataPlaneDiscovery(CrpcClientError),
}

Error related to the connection to the SNAP data plane.

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.

SnapTokenSourceMissing

Snap sockets cannot be bound without a SNAP token source.

TunnelEstablishment(ConnectSnapTunSocketError)

Error establishing the SNAP tunnel.

ControlPlaneClientCreation(CrpcClientCreationError)

Failed to create the SNAP control plane client.

DataPlaneDiscovery(CrpcClientError)

Failed to discover the SNAP data plane.

Implementations

impl SnapConnectionError

pub fn is_transient(&self) -> bool

Returns whether the failure is transient, so that a retry may help.

Prefer this over matching the variants: a new variant would silently fall into a caller’s wildcard arm.

Trait Implementations

impl Debug for SnapConnectionError

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

Formats the value using the given formatter.

impl Display for SnapConnectionError

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

Formats the value using the given formatter.

impl Error for SnapConnectionError

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.
