Struct harmonizer::CompositionErrorExtensions

pub struct CompositionErrorExtensions {
    pub code: String,
}

Mimicking the JavaScript-world from which this error comes, this represents the extensions property of a JavaScript GraphQLError from the [graphql-js] library. Such errors are created when errors have prevented successful composition, which is accomplished using errorWithCode. An example of this can be seen within the federation-js JavaScript library.

Fields

code: String

An Apollo Federation composition error code.

A non-exhaustive list of error codes that this includes, is:

• EXTERNAL_TYPE_MISMATCH
• EXTERNAL_UNUSED
• KEY_FIELDS_MISSING_ON_BASE
• KEY_MISSING_ON_BASE
• KEY_NOT_SPECIFIED
• PROVIDES_FIELDS_MISSING_EXTERNAL

…and many more! See the federation-js composition library for more details (and search for errorWithCode).
