Variants

ArrowSerialization(Error)

Tuple Fields

0: Error

An error has occurred when serializing to Arrow IPC format.

DataTypeMismatch

Fields

existing: DataType

The existing datatype of the field.

new: DataType

The datatype of the new data.

field: String

The name of the field.

There is a datatype mismatch in a field.

This can happen when calling Field::set_values with an array whose datatype does not match the existing array.

FieldLengthMismatch

Fields

lengths: Vec<(String, usize)>

The names and lengths of the fields in the Frame.

Occurs when a frame had mismatched field lengths while checking.

UnsupportedArrowDataType(DataType)

Tuple Fields

0: DataType

A field was created using an Arrow array with a datatype unsupported by Grafana.

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)>

The lower-level source of this error, if any.

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

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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
