Error for parsing and validating an interface.

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.

Parse(Error)

Couldn’t parse the interface JSON.

Schema(SchemaError)

Invalid InterfaceJson

Version(VersionError)

Invalid InterfaceVersion

Mapping(MappingError)

Couldn’t parse interface for an invalid mapping

Object(ObjectError)

Couldn’t parse object datastream interface

Name(InterfaceNameError)

Couldn’t parse interface name.

MissingTtl

The database retention policy is set to use_ttl but the TTL was not specified.

InvalidEndpoint(EndpointError)

Error while parsing the endpoint.

DuplicateMapping

The interfaced endpoints must all be unique.

Fields

endpoint: String

The existing endpoint.

duplicate: String

The duplicated endpoint.

NameMismatch

The name of the interface was changed.

Fields

name: String

The new version name.

prev_name: String

The previous version name.

VersionChange(VersionChangeError)

Invalid version change.

InterfaceConversion

Invalid interface type

Fields

exp_type: InterfaceType

The interface type we expected.

exp_aggregation: Aggregation

The aggregation we expected.

got_type: InterfaceType

The actual interface type.

got_aggregation: Aggregation

The actual aggregation.

PropertyObject

Unsupported interface type.

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>)
