Enum herbert::Error

pub enum Error {
    SendError(String),
    RecvError(String),
    NoSuchActor(String),
}

Errors that can occur.

Variants

SendError(String)

An error sending on a channel.

Converts the underlying crossbeam_channel::SendError into a string representation to make it easier, if less flexible, to deal with.

RecvError(String)

An error receiving on a channel.

Converts the underlying crossbeam_channel::RecvError into a string representation to make it easier, if less flexible, to deal with.

NoSuchActor(String)

The specified actor does not exist, or is not known to the router. Embeds the ID of the actor.

If an actor thread panics or otherwise chooses to stop, it is removed from the router and subsequent attempts to send messages to that actor will result in this error.

Methods

impl Error

pub fn send_error<T>(e: SendError<T>) -> Self

Construct an Error::SendError from an underlying crossbeam_channel::SendError<T>.

pub fn recv_error(e: RecvError) -> Self

Construct an Error::RecvError from an underlying crossbeam_channel::RecvError.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
