Enum OpenAIError 

#[non_exhaustive]
pub enum OpenAIError {
    Http(String),
    Api(String),
    Parse(String),
    Config(String),
    StreamInterrupted(String),
}

OpenAI error type

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.

Http(String)

HTTP request error

Api(String)

API-returned error

Parse(String)

Response parse error

Config(String)

Configuration error (missing/malformed environment variables, etc.).

StreamInterrupted(String)

The SSE stream ended before a terminal marker ([DONE], or a chunk carrying finish_reason) was observed — i.e. the connection dropped mid-generation. A12: the partial text streamed so far is truncated and must not be presented as a complete answer.

Trait Implementations

impl Debug for OpenAIError

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

Formats the value using the given formatter.

impl Display for OpenAIError

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

Formats the value using the given formatter.

impl Error for OpenAIError

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.

impl From<OpenAIError> for ProviderError

fn from(e: OpenAIError) -> Self

Converts to this type from the input type.

impl From<OpenAIError> for LcelError

Allow OpenAIError to convert into LcelError for LCEL pipeline compatibility.

OpenAIChat’s Runnable uses OpenAIError directly as its Error type; without the bridge, OpenAIChat cannot enter a pipe() chain (which needs R2::Error: Into<LcelError>). Qwen / DeepSeek go through OpenAI-compatible endpoints, but they wrap OpenAIError into ProviderError and bridge from there, already covered by the impl above.

fn from(err: OpenAIError) -> Self

Converts to this type from the input type.

impl From<ProviderError> for OpenAIError

fn from(e: ProviderError) -> Self

Converts to this type from the input type.

impl From<String> for OpenAIError

fn from(s: String) -> Self

Converts to this type from the input type.
