Struct EngineError 

pub struct EngineError {
    pub kind: EngineErrorKind,
    pub message: Option<String>,
}

A fully owned engine error: DuckDB’s own classification plus its message.

Pure Rust — every field is copied out of DuckDB memory when the error is built, so an EngineError stays valid after the handle it came from is destroyed and after the connection is closed.

Fields

kind: EngineErrorKind

How DuckDB classified the failure.

message: Option<String>

DuckDB’s message, if it supplied one.

Implementations

impl EngineError

pub fn unavailable(message: Option<String>) -> EngineError

Builds an engine error with no typed classification available.

Use for DuckDB APIs that expose only a status code and a message, so the absence of a kind is explicit rather than guessed.

Trait Implementations

impl Clone for EngineError

fn clone(&self) -> EngineError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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 Eq for EngineError

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 PartialEq for EngineError

fn eq(&self, other: &EngineError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
