Enum ErrorCategory 

#[non_exhaustive]
pub enum ErrorCategory {
    InvalidInput,
    Unauthorized,
    Forbidden,
    NotFound,
    RateLimited,
    Timeout,
    Unavailable,
    Cancelled,
    Internal,
    Unsupported,
}

Core traits and types.

Always available regardless of feature flags. Includes:

• Agent - The fundamental trait for all agents
• Tool / Toolset - For extending agents with capabilities
• Session / State - For managing conversation context
• Event - For streaming agent responses
• AdkError / Result - Unified error handling The kind of failure independent of subsystem.

Choose the variant that best describes what went wrong:

• InvalidInput — caller provided bad data (config, request body, parameters)
• Unauthorized — missing or invalid credentials
• Forbidden — valid credentials but insufficient permissions
• NotFound — requested resource does not exist
• RateLimited — upstream rate limit hit (retryable by default)
• Timeout — operation exceeded time limit (retryable by default)
• Unavailable — upstream service temporarily down (retryable by default)
• Cancelled — operation was cancelled by caller or system
• Internal — unexpected internal error (bugs, invariant violations)
• Unsupported — requested feature or operation is not supported

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.

Trait Implementations

impl Clone for ErrorCategory

fn clone(&self) -> ErrorCategory

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ErrorCategory

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ErrorCategory

fn deserialize<__D>( __deserializer: __D, ) -> Result<ErrorCategory, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ErrorCategory

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

Formats the value using the given formatter.

impl Hash for ErrorCategory

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ErrorCategory

fn eq(&self, other: &ErrorCategory) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ErrorCategory

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for ErrorCategory
