Enum grafana_plugin_sdk::data::Error

#[non_exhaustive]
pub enum Error {
    ArrowSerialization(Error),
    DataTypeMismatch {
        existing: DataType,
        new: DataType,
        field: String,
    },
    FieldLengthMismatch {
        lengths: Vec<(String, usize)>,
    },
    UnsupportedArrowDataType(DataType),
}

Errors that can occur when interacting with the Grafana plugin SDK.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ArrowSerialization(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)

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 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.
