Enum RustStreamError 

#[non_exhaustive]
pub enum RustStreamError {
    Connect(Box<dyn StdError + Send + Sync>),
    Startup(Box<dyn StdError + Send + Sync>),
    Subscribe(Box<dyn StdError + Send + Sync>),
    Shutdown(Box<dyn StdError + Send + Sync>),
    Join(JoinError),
    Dispatch(String),
}

Errors surfaced while running a RustStream 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.

Connect(Box<dyn StdError + Send + Sync>)

A broker failed to connect at startup.

Startup(Box<dyn StdError + Send + Sync>)

An on_startup or after_startup lifespan hook failed.

Subscribe(Box<dyn StdError + Send + Sync>)

A subscription failed to open after connect.

Shutdown(Box<dyn StdError + Send + Sync>)

A broker failed to shutdown during graceful shutdown.

Join(JoinError)

A dispatch task panicked or was aborted.

Dispatch(String)

A subscriber hit a fail-fast failure (a handler panic, or a decode failure under on_failure(decode = fail_fast)) and tore the service down. The string names the subscription and the reason.

Trait Implementations

impl Debug for RustStreamError

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

Formats the value using the given formatter.

impl Display for RustStreamError

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

Formats the value using the given formatter.

impl Error for RustStreamError

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<RustStreamError> for CliError

fn from(source: RustStreamError) -> Self

Converts to this type from the input type.
