Trait Implementations

impl Debug for ProcessorError

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

Formats the value using the given formatter.

impl Display for ProcessorError

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

Formats the value using the given formatter.

impl Error for ProcessorError

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<&str> for ProcessorError

Allow Err("literal".into()) patterns.

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<ProcessorError> for AkarError

fn from(e: ProcessorError) -> Self

Converts to this type from the input type.

impl From<ProcessorError> for String

Allow ? in functions still returning Result<T, String>.

fn from(e: ProcessorError) -> String

Converts to this type from the input type.

impl From<StorageError> for ProcessorError

Allow ? on StorageError in functions returning Result<T, ProcessorError>.

fn from(e: StorageError) -> Self

Converts to this type from the input type.

impl From<String> for ProcessorError

Allow Err("message".into()) patterns during incremental migration.

fn from(s: String) -> Self

Converts to this type from the input type.
