Enum DuckDbError 

pub enum DuckDbError {
    DuckDb(Error),
    Arrow(ArrowError),
    Schema(CoreError),
    Join(String),
    Other(String),
}

Unified error type for crate::DuckDbEngine operations.

Implements std::error::Error via thiserror and can be converted from several underlying error types using ?.

Variants

DuckDb(Error)

A native DuckDB error returned by the C++ engine (query execution, connection, Appender flush, etc.).

Arrow(ArrowError)

An Arrow record-batch construction or schema mismatch error.

Schema(CoreError)

A schema validation error from rhei_core (e.g. invalid identifier containing characters outside [A-Za-z0-9_]).

Join(String)

A tokio::task::spawn_blocking task panicked or was cancelled. The inner string is the stringified tokio::task::JoinError.

Other(String)

A catch-all error for situations not covered by the variants above.

Trait Implementations

impl Debug for DuckDbError

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

Formats the value using the given formatter.

impl Display for DuckDbError

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

Formats the value using the given formatter.

impl Error for DuckDbError

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.
