Expand description

Errors occurring when trying to interpret data passed from Grafana to this SDK.

Generally any errors should be considered a bug and should be reported.

Variants (Non-exhaustive)

This enum is marked as 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.

`MissingTimeRange`

The time_range was missing from the query.

`MissingPluginContext`

The plugin_context was missing from the request.

`InvalidJson`

Fields

err: Error

The underlying JSON error.

json: String

The JSON for which deserialization was attempted.

The JSON provided by Grafana was invalid.

`InvalidFrame`

Fields

source: Error

The underlying JSON error.

The frame provided by Grafana was malformed.

`InvalidRequest`

Fields

source: Error

The underlying http error.

The resource request was not a valid HTTP request.

`UnknownRole(String)`

The role string provided by Grafana didn’t match the roles known by the SDK.

`InvalidPath`

Fields

source: ChannelError

The underlying reason for the error.

The path provided by Grafana was invalid.
