Enum Error 

#[non_exhaustive]
pub enum Error {
    Io {
        source: Error,
        operation: IoOperation,
    },
    Type(TypeError),
    Timeout(TimeoutError),
    Protocol(ProtocolError),
    State(StateError),
}

Top-level error type for dstar-gateway-core.

All fallible operations in the core return Result<_, Error>. Pattern-match this enum to distinguish I/O failures from timeouts from protocol errors from type-validation errors.

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.

Io

Underlying I/O failure on a socket or TCP stream.

Only emitted by the shell crates — dstar-gateway-core itself has no I/O. Carried here for the shell crates’ convenience.

Fields

source: Error

Underlying std::io::Error.

operation: IoOperation

What kind of I/O the operation was.

Type(TypeError)

Construction-time validation failure (Callsign, Module, etc.).

Timeout(TimeoutError)

A typed deadline-exceeded error.

Protocol(ProtocolError)

Protocol-level error (per-protocol structured cause).

State(StateError)

State-machine residual that the typestate cannot prevent.

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, __formatter: &mut Formatter<'_>) -> Result

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<ProtocolError> for Error

fn from(source: ProtocolError) -> Self

Converts to this type from the input type.

impl From<StateError> for Error

fn from(value: StateError) -> Self

Converts to this type from the input type.

impl From<TimeoutError> for Error

fn from(value: TimeoutError) -> Self

Converts to this type from the input type.

impl From<TypeError> for Error

fn from(source: TypeError) -> Self

Converts to this type from the input type.
