Enum CodeError 

pub enum CodeError {
    Config(String),
    Llm(String),
    Tool {
        tool: String,
        message: String,
    },
    Session(String),
    Security(String),
    Context(String),
    Mcp(String),
    Queue(String),
    Io(Error),
    Serialization(Error),
    Internal(Error),
}

Categorized error type for A3S Code Core.

SDK bindings (Python/Node) can match on the variant to expose typed exceptions (e.g., CodeConfigError, CodeLlmError).

Variants

Config(String)

Configuration loading or parsing error

Llm(String)

LLM provider communication error

Tool

Tool execution error

Fields

tool: String

message: String

Session(String)

Session management error

Security(String)

Security subsystem error

Context(String)

Context provider or context store error

Mcp(String)

MCP (Model Context Protocol) error

Queue(String)

Queue or lane error

Io(Error)

I/O error

Serialization(Error)

JSON serialization/deserialization error

Internal(Error)

Catch-all for errors not yet migrated to a specific variant.

The #[from] anyhow::Error conversion enables gradual migration: any function returning anyhow::Result can be called with ? from a function returning crate::error::Result without changes.

Trait Implementations

impl Debug for CodeError

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

Formats the value using the given formatter.

impl Display for CodeError

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

Formats the value using the given formatter.

impl Error for CodeError

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<Error> for CodeError

fn from(source: Error) -> Self
