Enum SageError 

pub enum SageError {
    Llm(String),
    Agent(String),
    Type {
        expected: String,
        got: String,
    },
    Http(Error),
    Json(Error),
    JoinError(String),
    Tool(String),
    Io(Error),
    User(String),
    Supervisor(String),
    Protocol(String),
}

Error type for Sage runtime errors.

RFC-0007: This is exposed to Sage programs as the Error type with .message and .kind field accessors.

Variants

Llm(String)

Error from LLM inference.

Agent(String)

Error from agent execution.

Type

Type mismatch at runtime.

Fields

expected: String

got: String

Http(Error)

HTTP request error.

Json(Error)

JSON parsing error.

JoinError(String)

Agent task was cancelled or panicked.

Tool(String)

RFC-0011: Error from tool execution.

Io(Error)

I/O error (file operations, etc.).

User(String)

User-raised error via fail expression.

Supervisor(String)

Error from supervisor (restart intensity exceeded, etc.).

Protocol(String)

Phase 3: Protocol violation in session types.

Implementations

impl SageError

pub fn message(&self) -> String

RFC-0007: Get the error message as a String.

This is exposed to Sage programs as e.message.

pub fn kind(&self) -> ErrorKind

RFC-0007: Get the error kind classification.

This is exposed to Sage programs as e.kind.

pub fn llm(msg: impl Into<String>) -> Self

Create an LLM error with a message.

pub fn agent(msg: impl Into<String>) -> Self

Create an agent error with a message.

pub fn type_error(expected: impl Into<String>, got: impl Into<String>) -> Self

Create a type error.

pub fn tool(msg: impl Into<String>) -> Self

RFC-0011: Create a tool error with a message.

pub fn user(msg: impl Into<String>) -> Self

Create a user error via fail expression.

pub fn protocol(msg: impl Into<String>) -> Self

Phase 3: Create a protocol violation error.

Trait Implementations

impl Debug for SageError

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

Formats the value using the given formatter.

impl Display for SageError

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

Formats the value using the given formatter.

impl Error for SageError

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.
