Enum AdkError 

pub enum AdkError {
    Agent(String),
    Model(String),
    Tool(String),
    Session(String),
    Artifact(String),
    Memory(String),
    Config(String),
    Io(Error),
    Serde(Error),
}

Unified error type for all ADK operations.

Each variant corresponds to a layer in the framework. Prefer the most specific variant (e.g. Tool over Agent) so callers can match on the source of failure.

Variants

Agent(String)

Error originating from agent execution or orchestration.

Model(String)

Error from an LLM provider (network, auth, rate limit, bad response).

Tool(String)

Error from tool execution or schema validation.

Session(String)

Error from session creation, retrieval, or state persistence.

Artifact(String)

Error from artifact storage or retrieval.

Memory(String)

Error from the long-term memory / RAG subsystem.

Config(String)

Invalid or missing configuration (API keys, model names, etc.).

Io(Error)

Filesystem or network I/O error.

Serde(Error)

JSON serialization or deserialization error.

Trait Implementations

impl Debug for AdkError

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

Formats the value using the given formatter.

impl Display for AdkError

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

Formats the value using the given formatter.

impl Error for AdkError

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.
