Available on crate feature unstable only.

Internal errors that can occur with ESP-NOW.

Stability

This API is marked as unstable and is only available when the unstable crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.

Variants

NotInitialized = 12_389

ESP-NOW is not initialized.

InvalidArgument = 12_390

Invalid argument.

OutOfMemory = 12_391

Indicates that there was insufficient memory to complete the operation.

PeerListFull = 12_392

ESP-NOW peer list is full.

NotFound = 12_393

ESP-NOW peer is not found.

Internal = 12_394

Internal error.

PeerExists = 12_395

ESP-NOW peer already exists.

InterfaceMismatch = 12_396

The Wi-Fi interface used for ESP-NOW doesn’t match the expected one for the peer.

Other(u32)

Represents any other error not covered by the above variants, with an associated error code.

Implementations

impl Error

pub fn from_code(code: u32) -> Error

Create an Error from a raw error code.

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

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 Format for Error

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.
