Enum SnapConnectionError 

#[non_exhaustive]
pub enum SnapConnectionError {
    SnapTokenSourceMissing,
    TunnelEstablishment(Box<dyn Error + Send + Sync>),
    ControlPlaneClientCreation(Box<dyn Error + Send + Sync>),
    DataPlaneDiscovery(Box<dyn Error + Send + Sync>),
}

Error related to the connection to the SNAP data plane.

The underlying cause of the client/discovery variants is available through std::error::Error::source; the concrete source types are intentionally not exposed.

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(Box<dyn Error + Send + Sync>)

Error establishing the SNAP tunnel.

ControlPlaneClientCreation(Box<dyn Error + Send + Sync>)

Failed to create the SNAP control plane client.

DataPlaneDiscovery(Box<dyn Error + Send + Sync>)

Failed to discover the SNAP data plane.

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>)
