Enum Error 

pub enum Error {
    Unknown,
    NoResult,
    ConnectionFailed,
    InvalidData(String),
    PathError,
    Io(Error),
    Nul(NulError),
    InsufficientPermissions,
    NonUtf8Sequence(FromUtf8Error),
    QueryError(String),
}

Errors that can occur when using chdb-rust.

This enum represents all possible errors that can be returned by the library. Most errors are self-explanatory, with QueryError containing the actual error message from the underlying chDB library.

Variants

Unknown

An unknown error has occurred.

NoResult

No result was returned from the query.

ConnectionFailed

Failed to establish a connection to chDB.

InvalidData(String)

Invalid data was encountered.

PathError

Invalid path was provided.

Io(Error)

An I/O error occurred.

Nul(NulError)

A null byte was found in a string where it’s not allowed.

InsufficientPermissions

Insufficient permissions to access the directory.

NonUtf8Sequence(FromUtf8Error)

The data contains invalid UTF-8 sequences.

QueryError(String)

A query execution error occurred.

This contains the error message from the underlying chDB library, which typically includes details about SQL syntax errors, missing tables, etc.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<NulError> for Error

fn from(source: NulError) -> Self

Converts to this type from the input type.
