Enum AgentError 

#[non_exhaustive]
pub enum AgentError {
    MaxIterationsExceeded(u32),
    ToolNotFound {
        name: String,
    },
    ToolFailed {
        name: String,
        reason: String,
    },
    ParseError(String),
    Timeout {
        timeout_ms: u64,
    },
    HistoryOverflow {
        size: usize,
        limit: usize,

    Serialization(String),
    InvalidToolSignature(String),
}

All errors that can occur in the wasm-agent ReAct loop.

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.

MaxIterationsExceeded(u32)

The agent ran the maximum number of iterations without producing a final answer.

ToolNotFound

A tool was requested that does not exist in the registry.

Fields

name: String

Tool name.

ToolFailed

A tool was found but its execution failed.

Fields

name: String

Tool name.

reason: String

What went wrong.

ParseError(String)

The LLM response could not be parsed as a valid ReAct step.

Timeout

The agent exceeded its wall-clock time budget.

Fields

timeout_ms: u64

The time budget in milliseconds.

HistoryOverflow

The conversation history exceeded its token budget.

Fields

size: usize

Tokens the history would have had.

limit: usize

The token limit.

Serialization(String)

A value could not be serialized.

InvalidToolSignature(String)

A tool was registered with an invalid signature.

Trait Implementations

impl Clone for AgentError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AgentError

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

Formats the value using the given formatter.

impl Display for AgentError

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

Formats the value using the given formatter.

impl Error for AgentError

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.
