External

External error passed through from user code.

This variant preserves errors that users pass into Lance APIs (e.g., via streams with custom error types). The original error can be recovered using Error::into_external or inspected using Error::external_source.

Implementations

impl Error

pub fn corrupt_file( path: Path, message: impl Into<String>, location: Location, ) -> Error

pub fn invalid_input(message: impl Into<String>, location: Location) -> Error

pub fn io(message: impl Into<String>, location: Location) -> Error

pub fn version_conflict( message: impl Into<String>, major_version: u16, minor_version: u16, location: Location, ) -> Error

pub fn not_found(uri: impl Into<String>) -> Error

pub fn schema(message: impl Into<String>, location: Location) -> Error

pub fn not_supported(message: impl Into<String>, location: Location) -> Error

pub fn external(source: Box<dyn Error + Sync + Send>) -> Error

Create an External error from a boxed error source.

pub fn external_source(&self) -> Option<&Box<dyn Error + Sync + Send>>

Returns a reference to the external error source if this is an External variant.

This allows downcasting to recover the original error type.

pub fn into_external(self) -> Result<Box<dyn Error + Sync + Send>, Error>

Consumes the error and returns the external source if this is an External variant.

Returns Err(self) if this is not an External variant, allowing for chained handling.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

where Error: Debug + Display,

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 source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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 ErrorCompat for Error

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.
