Enum VerifyError 

pub enum VerifyError {
    InvalidAuthentication,
    ProviderError(String),
    ProviderResponse(ProviderResponseError),
    HttpError(Error),
}

Errors from provider client verification.

Inspect provider failures with Self::provider_response_body, Self::provider_response_json, and Self::provider_response_status.

Note: no provider path currently constructs Self::ProviderResponse for verification; real verify failures surface as Self::HttpError, which the helpers read. The variant is kept for symmetry with the other capability errors and for future provider paths that preserve a 2xx error envelope.

Variants

InvalidAuthentication

ProviderError(String)

ProviderResponse(ProviderResponseError)

Raw error response preserved from the provider

HttpError(Error)

Implementations

impl VerifyError

pub fn from_http_response(status: StatusCode, body: impl Into<String>) -> Self

Builds an error from a captured HTTP status and raw response body, routing it so the provider_response_* helpers stay useful.

This is the single funnel every HTTP-error path should use instead of flattening a status and body into a ProviderError(String):

• A success (2xx) status carries a provider-authored error envelope, so it is preserved as Self::ProviderResponse together with the status.
• A non-success status is preserved as Self::HttpError(http_client::Error::InvalidStatusCodeWithMessage).

Either way the raw body is kept verbatim and the status stays recoverable through Self::provider_response_status. Read the response body exactly once and hand it here for both branches.

pub fn from_http_response_with_request_id( status: StatusCode, body: impl Into<String>, provider_request_id: Option<String>, ) -> Self

Self::from_http_response for paths that captured the provider’s transport request id alongside the response (rig#2314).

Unlike the metadata-less funnel, a non-success status is preserved as Self::ProviderResponse too — http_client’s error type has no slot for provider metadata, and the id the provider reported on a failed call is exactly what support asks for. Classification therefore follows the code path (did this call site capture transport metadata?), never the presence of the header on a particular response, so a given provider’s errors classify consistently. The status stays recoverable through Self::provider_response_status and the id through Self::provider_request_id.

pub fn with_response_headers(self, headers: Option<Box<HeaderMap>>) -> Self

Attaches the response’s headers to an error just built by one of the from_http_response* funnels, so rate-limit metadata (Retry-After, x-ratelimit-*) survives onto it (rig#2210).

This is a separate step rather than a funnel parameter because the funnels’ classification is fixed by the call path (does this provider have a request-id contract?), while header capture depends only on whether the transport handed the response back. Both routes can therefore carry headers: Self::ProviderResponse stores them alongside the request id, and a non-success Self::HttpError is upgraded in place to http_client::Error::InvalidStatusCodeWithDetails, which displays identically to the header-less variant.

Passing None leaves the error untouched, as does calling this on a variant with no response to annotate. An error that already captured headers keeps the ones it has: the first capture is the one that saw the response, so this never overwrites.

pub fn from_provider_body(body: impl Into<String>) -> Self

Preserves a raw provider error body that has no HTTP status.

Use this for non-HTTP transports (gRPC / SDK clients such as AWS Bedrock, Vertex AI, or the gRPC Gemini client) where the provider returns an error payload but no http::StatusCode is available. The body is preserved as Self::ProviderResponse with status == None, so Self::provider_response_body still surfaces it while Self::provider_response_status returns None.

pub fn provider_response_body(&self) -> Option<&str>

Returns the raw provider response body when available.

This is available for:

• Self::ProviderResponse using its preserved body.
• Self::HttpError when it wraps an HTTP non-success response that carries a body.

Returns None for any other variant — for example a Rig-generated ProviderError diagnostic, or a failure from a transport with no provider response body to preserve. An empty preserved body is reported as Some("") (the provider returned no payload), which is distinct from None; note that Self::provider_response_json maps that same empty body to Ok(None).

pub fn provider_response_json(&self) -> Result<Option<Value>, Error>

Parses the provider response body as JSON.

Returns:

• Ok(Some(value)) when a body is present and valid JSON.
• Ok(None) when no provider response body is available.
• Err(error) when a body is present but isn’t valid JSON.

pub fn provider_response_status(&self) -> Option<StatusCode>

Returns the HTTP status code when this error preserves one, either from a non-success HTTP response, from a preserved provider response, or from a 2xx error envelope.

Warning: this can return a 2xx status. Some providers send an error envelope alongside a success status, which Rig preserves via Self::ProviderResponse. Callers must not infer failure from the status code alone — the existence of this error already means the call failed. Returns None for non-HTTP transports (gRPC / SDK clients) and for variants that carry no provider response.

pub fn provider_request_id(&self) -> Option<&str>

Returns the provider’s transport request id for the failed call, when the capture path preserved one (rig#2314) — the id provider support asks for. None for providers that report none, for paths that captured no transport metadata, and for errors with no provider response at all.

pub fn provider_response_headers(&self) -> Option<&HeaderMap>

Returns the response’s headers when the capture path preserved them (rig#2210) — the rate-limit metadata (Retry-After, x-ratelimit-*) a caller needs to back off correctly:

fn backoff(error: &CompletionError) -> Option<Duration> {
    let seconds = error
        .provider_response_headers()?
        .get(http::header::RETRY_AFTER)?
        .to_str()
        .ok()?
        .parse()
        .ok()?;
    Some(Duration::from_secs(seconds))
}

Returns None when no headers were captured: non-HTTP transports (gRPC / SDK clients), Rig-generated diagnostics, errors funnelled from only a status and body (e.g. via Self::from_http_response), and transports that report a non-success status without preserving them. None therefore means “not captured”, never “the response had no headers”.
