Enum Error 

#[non_exhaustive]
pub enum Error {
    Transport(String),
    Io(String),
    Codec(String),
    Closed,
    Auth(String),
    Unsupported(&'static str),
}

The error type returned by all fallible pamoja operations.

This enum is #[non_exhaustive]: new variants may be added in future releases without a breaking change, so downstream match expressions must include a wildcard arm.

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.

Transport(String)

A transport-level failure while connecting, sending, or receiving.

The payload is a human-readable description provided by the transport.

Io(String)

A device or peripheral input/output operation failed.

The payload is a human-readable description of the I/O fault.

Codec(String)

A payload could not be encoded or decoded.

The payload describes the encoding or decoding fault.

Closed

The operation targeted a resource that is closed or disconnected.

Auth(String)

A security check failed, such as an invalid identity or a bad signature.

The payload describes the authentication or integrity fault.

Unsupported(&'static str)

The requested capability is not compiled into this build.

The payload names the missing capability, for example "mqtt".

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

Formats the value using the given formatter.

impl Error for Error

Available on crate feature std only.

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.
