Errors returned when backend metadata fails the shared consistency checks.

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.

BlankField

A required metadata field is blank or whitespace-padded.

Fields

field: &'static str

Name of the offending metadata field.

EmptyField

A required list field is empty.

Fields

field: &'static str

Name of the offending metadata list field.

DuplicateEntry

A catalog-style list field contains a duplicate entry.

Fields

field: &'static str

Name of the metadata list field that held the duplicate.

value: String

The duplicated entry value.

NominalRangeNotFinite

The nominal range contains a non-finite Julian-day bound.

NominalRangeScaleMismatch

The nominal range bounds use different time scales.

NominalRangeOutOfOrder

The nominal range end precedes the start.

InvalidCapabilities

The declared capability flags are internally inconsistent.

Fields

field: &'static str

The invalid field name.

message: &'static str

A short description of the capability mismatch.
