Enum ComponentError 

pub enum ComponentError {
    Tool(Error),
    Internal(Error),
}

Errors from component calls.

The split is what a host has to act on: Self::Tool is the component answering — it ran, and it said no — while Self::Internal is the host failing to run it at all. Reporting one as the other is how a sandbox failure comes to look like a tool’s opinion.

Variants

Tool(Error)

Structured tool error from the component (has kind, message, metadata).

Internal(Error)

Infrastructure error (wasmtime, actor channel, etc.).

Trait Implementations

impl Debug for ComponentError

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

Formats the value using the given formatter.

impl Display for ComponentError

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

Formats the value using the given formatter.

impl Error for ComponentError

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.
