Enum CopilotRequestError 

#[non_exhaustive]
pub enum CopilotRequestError {
    ConnectionClosed,
    InvalidState(String),
    Upstream(String),
    Handler(String),
    Rpc(Error),
}

Error returned by a CopilotRequestHandler hook or the response stream.

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.

ConnectionClosed

The response was used after the RPC connection to the runtime closed.

InvalidState(String)

The response state machine was violated (for example start called twice, or a write before start).

Upstream(String)

An upstream transport failure while forwarding the request.

Handler(String)

A failure surfaced by the consumer’s own handler.

Rpc(Error)

An RPC error talking to the runtime.

Implementations

impl CopilotRequestError

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

Construct a handler-level error from a message — the idiomatic way for a consumer to fail an intercepted request.

Trait Implementations

impl Debug for CopilotRequestError

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

Formats the value using the given formatter.

impl Display for CopilotRequestError

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

Formats the value using the given formatter.

impl Error for CopilotRequestError

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 CopilotRequestError

fn from(err: Error) -> Self

Converts to this type from the input type.
