Enum AppServerError 

pub enum AppServerError {
    InterruptedByUser(String),
    LockPoisoned {
        provider: &'static str,
    },
    PromptRender(String),
    Provider(String),
    RetryExhausted {
        provider: &'static str,
        first_error: String,
        retry_error: String,
    },
    Transport(AppServerTransportError),
}

Typed error returned by app-server infrastructure operations.

Wraps transport failures, prompt rendering issues, lock errors, and provider-specific failures so callers can distinguish error categories without parsing opaque strings.

Variants

InterruptedByUser(String)

The user interrupted an in-flight app-server turn.

LockPoisoned

The session registry mutex is poisoned.

Fields

provider: &'static str

Provider label for diagnostics.

PromptRender(String)

A prompt template or protocol instruction rendering failed.

Provider(String)

A provider-specific runtime startup or turn execution failure.

RetryExhausted

Both the initial attempt and one retry after restart failed.

Fields

provider: &'static str

Provider label for diagnostics.

first_error: String

Error message from the first failed attempt.

retry_error: String

Error message from the retry attempt after restart.

An stdio transport or process communication failure.

Trait Implementations

impl Debug for AppServerError

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

Formats the value using the given formatter.

impl Display for AppServerError

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

impl Error for AppServerError

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<AppServerError> for AgentError
