Enum Error 

#[non_exhaustive]
pub enum Error {
    Network {
        message: String,
    },
    Auth {
        message: String,
    },
    Rejected {
        message: String,
    },
    Parse {
        message: String,
    },
    Unsupported {
        message: String,
    },
}

Typed error for every shelly-core transport path.

The five variants map 1:1 onto switchkit::Error: a caller that already speaks that vocabulary can translate this enum without guesswork.

#[non_exhaustive] because the error taxonomy is expected to grow; this is free to add now and a breaking change to add later, for a crate about to publish its first crates.io release.

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.

Network

The device could not be reached at all (connect/timeout/read failure), or it responded with a non-success HTTP status that is not an auth failure.

Fields

message: String

Auth

The device rejected the request because of missing or invalid credentials (HTTP 401/403).

Fields

message: String

Rejected

The device was reached, answered with a well-formed response, but explicitly rejected the request (a Gen2 RPC error object in an HTTP 200 body).

Fields

message: String

Parse

The device was reached but its response could not be interpreted: invalid JSON, or a /shelly body that does not describe a Shelly device. Reachable-but-not-Shelly is deliberately Parse, not Network, so callers can distinguish “nothing there” from “something else is there”.

Fields

message: String

Unsupported

The operation is genuinely not supported, either by this device generation or by this client (replaces the old anyhow::bail!("not supported") paths).

Fields

message: String

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<Error> for Error

Classify a raw reqwest::Error into a typed Error.

reqwest::Error already distinguishes response-decode failures (is_decode) from connect/timeout/request-level failures, so a plain ? on send()/json() calls routes through this impl and lands on the right variant without every call site repeating the classification.

fn from(err: Error) -> Self

Converts to this type from the input type.
