Enum LlmError 

#[non_exhaustive]
pub enum LlmError {
    Api {
        status: u16,
        message: String,
    },
    Auth(String),
    Transport(String),
    Config(String),
    RequestFailed(String),
    ModelNotAvailable(String),
    RateLimited,
    ContentFiltered(String),
    Other(String),
}

Errors from LLM operations.

Errors keep what the provider said — the HTTP status, the reason content was blocked — so a caller can decide what to do without parsing a message:

use gemini_adk_rs::llm::LlmError;

let err = LlmError::Api { status: 429, message: "quota exceeded".into() };
assert!(err.is_rate_limited() && err.is_retryable());
assert_eq!(err.status(), Some(429));

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.

Api

The provider answered with an error status.

Fields

status: u16

The HTTP status code.

message: String

The provider’s error message.

Auth(String)

Credentials are missing or were rejected. The message says how to fix it.

Transport(String)

The provider could not be reached: connection, TLS or timeout.

Config(String)

The client is configured in a way no request can succeed with. The message says what to change.

RequestFailed(String)

The HTTP request to the LLM API failed for another reason.

ModelNotAvailable(String)

The requested model is not available.

RateLimited

The request was rate-limited by the provider.

ContentFiltered(String)

The prompt or the reply was blocked by content safety; carries the provider’s reason (e.g. "SAFETY", "PROHIBITED_CONTENT").

Other(String)

A catch-all for other LLM errors.

Implementations

impl LlmError

pub fn status(&self) -> Option<u16>

The HTTP status the provider answered with, when there was one.

pub fn is_rate_limited(&self) -> bool

The provider is rate-limiting or out of quota (HTTP 429).

pub fn is_auth(&self) -> bool

Credentials are missing, invalid or lack permission (HTTP 401/403).

pub fn is_content_filtered(&self) -> bool

The prompt or reply was blocked by content safety.

pub fn is_retryable(&self) -> bool

Trying the same request again later may succeed: rate limits, server errors (5xx) and transport failures. Auth, configuration, content safety and other client errors will fail the same way again.

Trait Implementations

impl Debug for LlmError

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

Formats the value using the given formatter.

impl Display for LlmError

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

Formats the value using the given formatter.

impl Error for LlmError

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<LlmError> for AgentError

fn from(source: LlmError) -> AgentError

Converts to this type from the input type.
