Why a device could not do what it was asked.

Variants

TooManyChannels

The plan defines more channels than a device keeps.

Fields

max: usize

The most a device keeps, MAX_CHANNELS.

NoCredentials

A device activated by personalization has nothing to join with.

NotJoined

The device has not joined.

Busy

A transmission is still waiting on its receive windows.

NothingPending

There is no transmission waiting on its windows or due to repeat.

Wait

The air is not free until this time, in the caller’s microseconds.

Fields

until_us: u64

The earliest time to try again.

NoChannel

No enabled channel carries the data rate, and restoring the defaults did not help.

DataRate(u8)

The data rate is not a LoRa one this device can send or hear.

PayloadTooLong

The payload does not fit a frame at the current data rate.

Fields

max: usize

The most the frame can carry, in bytes.

CounterExhausted

The uplink frame counter has reached its end, and the device has to join again.

Frame(LorawanError)

The frame did not decode.

Foreign

The frame is addressed to another device.

Replayed

The frame repeats or precedes the last downlink the device accepted.

CounterGap

The frame is further ahead of the last downlink than LoRaWAN 1.0.3 lets a device follow.

Refused

A join accept carries settings the region does not allow, which RP002-1.0.5 has a device ignore.

State(StateError)

A saved state could not be resumed.

Trait Implementations

impl Clone for DeviceError

fn clone(&self) -> DeviceError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DeviceError

impl Debug for DeviceError

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

Formats the value using the given formatter.

impl Display for DeviceError

impl Eq for DeviceError

impl Error for DeviceError

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<DeviceError> for RelayError

fn from(error: DeviceError) -> RelayError

Converts to this type from the input type.

impl From<LorawanError> for DeviceError

fn from(error: LorawanError) -> DeviceError

Converts to this type from the input type.

impl PartialEq for DeviceError

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

Equality operator ==.

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

Inequality operator !=.
