Error surface for text-generation adapters.

Marked #[non_exhaustive] so provider crates can grow their own failure modes without a breaking change here.

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.

Network(String)

Auth(String)

Provider rejected credentials.

RateLimited(String)

Provider rate-limited the request.

BadRequest

4xx from the provider.

Fields

status: u16

HTTP status code.

body: String

Server

5xx from the provider.

Fields

status: u16

HTTP status code.

body: String

Decode(String)

Response decoder failed (malformed JSON, missing content field, …).

Config(String)

Adapter config invalid (bad URL, missing env var, etc.).

EmptyCompletion
