Enum capnp::ErrorKind

pub enum ErrorKind {
    Failed,
    Overloaded,
    Disconnected,
    Unimplemented,
}

The general nature of an error. The purpose of this enum is not to describe the error itself, but rather to describe how the client might want to respond to the error.

Variants

Failed

Something went wrong. This is the usual error kind. It includes decoding errors.

Overloaded

The call failed because of a temporary lack of resources. This could be space resources (out of memory, out of disk space) or time resources (request queue overflow, operation timed out).

The operation might work if tried again, but it should NOT be repeated immediately as this may simply exacerbate the problem.

Disconnected

The call required communication over a connection that has been lost. The callee will need to re-establish connections and try again.

Unimplemented

The requested method is not implemented. The caller may wish to revert to a fallback approach based on other methods.

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> ErrorKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl PartialEq<ErrorKind> for ErrorKind

fn eq(&self, other: &ErrorKind) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
