Enum CallError 

#[non_exhaustive]
pub enum CallError<E> {
    Domain(E),
    Deadline,
    Cancelled,
    Unavailable(Detail),
    ContractViolation(Detail),
    InvalidResponse(Detail),
    Internal(Detail),
}

A typed domain outcome or failure to complete or interpret a call.

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.

Domain(E)

The capability returned its declared domain error.

Deadline

The call deadline expired.

Cancelled

The call was cancelled.

Unavailable(Detail)

The target was unavailable.

ContractViolation(Detail)

Caller input violated the contract.

InvalidResponse(Detail)

The provider produced an invalid response.

Internal(Detail)

The invocation failed internally.

Trait Implementations

impl<E: Clone> Clone for CallError<E>

fn clone(&self) -> CallError<E>

Returns a duplicate of the value.

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

impl<E: Eq> Eq for CallError<E>

impl<E: Debug> Error for CallError<E>

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
