Enum Error 

pub enum Error {
    Io(Error),
    Json(Error),
    Internal(String),
}

Errors returned by Spectra storage, routing, serialization, and I/O paths.

Backend-specific failures that do not map to I/O or JSON are reported as Internal with their original message.

Examples

use spectra_core::Error;

let error = Error::Internal("metrics backend is required".into());
assert_eq!(error.to_string(), "metrics backend is required");

match error {
    Error::Internal(message) => assert!(message.contains("backend")),
    Error::Io(_) | Error::Json(_) => unreachable!(),
}

Variants

Io(Error)

Underlying filesystem or stream I/O failure.

Json(Error)

JSON serialization or deserialization failure.

Internal(String)

Catch-all internal error with a message.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(source: Error) -> Error

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Error

Converts to this type from the input type.
