Enum AttachError 

pub enum AttachError {
    SnapshotFailed(String),
    SubscribeFailed(String),
    NoSuchEntity(String),
    Transport(String),
}

Errors that can occur during an attach lifecycle.

Distinct from per-consumer errors (producer disconnect, malformed frame, etc.) which surface through the consumer’s consume impl and are not engate’s concern.

Variants

SnapshotFailed(String)

The producer’s snapshot operation failed. Engate cannot reach Synced without a snapshot.

SubscribeFailed(String)

Subscribing to the live stream failed.

NoSuchEntity(String)

The producer reports the requested entity does not exist.

Transport(String)

Generic transport / I/O error during attach.

Trait Implementations

impl Debug for AttachError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AttachError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for AttachError

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

Formats the value using the given formatter.

impl Error for AttachError

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 Serialize for AttachError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
