Enum ProviderError 

pub enum ProviderError {
    OpenAI(OpenAIError),
    Anthropic(AnthropicError),
    Gemini(GeminiError),
    Azure(AzureOpenAIError),
    Cohere(CohereError),
    Ollama(OllamaError),
    Assistant(AssistantError),
    Responses(ResponsesError),
}

Unified error type that aggregates all LLM provider errors.

This allows using ? across provider boundaries without manually mapping error types. Each variant wraps the original provider error, preserving full context.

Variants

OpenAI(OpenAIError)

OpenAI API error.

Anthropic(AnthropicError)

Anthropic API error.

Gemini(GeminiError)

Gemini API error.

Azure(AzureOpenAIError)

Azure OpenAI API error.

Cohere(CohereError)

Cohere API error.

Ollama(OllamaError)

Ollama API error.

Assistant(AssistantError)

OpenAI Assistants API error.

Responses(ResponsesError)

OpenAI Responses API error.

Trait Implementations

impl Debug for ProviderError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ProviderError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ProviderError

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>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
