Enum SetError 

#[non_exhaustive]
pub enum SetError {
    NotConnected,
    UnknownDevice,
    UnknownProperty,
    NotSettable,
    DeviceNotReady(DeviceState),
    Invalid(Problem),
    InvalidTopic,
}

Available on crate feature alloc only.

Why a /set or $broadcast was not sent.

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.

NotConnected

The broker link is down; QoS 0 is never held (convention.md:695).

UnknownDevice

No device with that id is known.

UnknownProperty

The device has no model, or declares no such property.

NotSettable

The property is not settable.

DeviceNotReady(DeviceState)

The device’s effective state is not ready (convention.md:279).

Invalid(Problem)

The payload fails the check the device runs.

InvalidTopic

A $broadcast subtopic level is not a valid id, or the domain is Domain::Any.

Implementations

impl SetError

pub const fn as_str(self) -> &'static str

camelCase reason code.

Trait Implementations

impl Clone for SetError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for SetError

impl Debug for SetError

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

Formats the value using the given formatter.

impl Display for SetError

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

Formats the value using the given formatter.

impl Eq for SetError

impl Error for SetError

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 Hash for SetError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SetError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
