Enum ExecutorError 

pub enum ExecutorError {
    Io(Error),
    SpawnFailed(String),
    ExecutionFailed(String),
    SessionNotFound(String),
    InvalidConfig(String),
    Unavailable(String),
    Serialization(Error),
    Other(String),
}

Error type for executor lifecycle, transport, session, and normalization failures.

The variants are intentionally coarse enough to stay stable across providers, while still allowing callers to branch on the failure phase.

Variants

Io(Error)

Underlying I/O error while interacting with local files or subprocess pipes.

SpawnFailed(String)

Executor process or SDK client could not be created.

ExecutionFailed(String)

Executor process ran but the request failed during execution.

SessionNotFound(String)

Requested session identifier is unknown to the executor backend.

InvalidConfig(String)

User-provided or resolved configuration is invalid.

Unavailable(String)

Executor binary or required runtime dependency is unavailable.

Serialization(Error)

JSON serialization or deserialization failed.

Other(String)

Miscellaneous error not covered by the typed variants above.

Implementations

impl ExecutorError

pub fn error_type(&self) -> &'static str

Returns a stable machine-readable error category.

This is useful when logging or exporting metrics across different provider backends without depending on formatted error messages.

pub fn spawn_failed(context: impl AsRef<str>, error: impl Display) -> Self

Builds ExecutorError::SpawnFailed with contextual operation details.

pub fn execution_failed(context: impl AsRef<str>, error: impl Display) -> Self

Builds ExecutorError::ExecutionFailed with contextual operation details.

pub fn invalid_config(context: impl AsRef<str>, error: impl Display) -> Self

Builds ExecutorError::InvalidConfig with contextual operation details.

pub fn unavailable(context: impl AsRef<str>, error: impl Display) -> Self

Builds ExecutorError::Unavailable with contextual operation details.

pub fn other(context: impl AsRef<str>, error: impl Display) -> Self

Builds ExecutorError::Other with contextual operation details.

Trait Implementations

impl Debug for ExecutorError

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

Formats the value using the given formatter.

impl Display for ExecutorError

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

Formats the value using the given formatter.

impl Error for ExecutorError

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<Error> for ExecutorError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for ExecutorError

fn from(source: Error) -> Self

Converts to this type from the input type.
