Enum EngineError 

pub enum EngineError {
    User(String),
    Internal(String),
    Io(String),
    Sql(String),
    NotFound(String),
    Other(String),
}

Unified error type for robin-sparkless operations.

Embedders (Python, Node, CLI) can map these variants to native errors without depending on PolarsError.

Variants

User(String)

User-facing error (invalid input, unsupported operation).

Internal(String)

Internal / compute error.

Io(String)

I/O error (file not found, permission, etc.).

Sql(String)

SQL parsing or execution error.

NotFound(String)

Resource not found (column, table, file).

Other(String)

Other / unclassified.

Trait Implementations

impl Debug for EngineError

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

Formats the value using the given formatter.

impl Display for EngineError

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

Formats the value using the given formatter.

impl Error for EngineError

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 EngineError

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<Error> for EngineError

fn from(e: Error) -> Self
