Enum EspNowError 

pub enum EspNowError {
    Error(Error),
    SendFailed,
    DuplicateInstance,
    Initialization(WifiError),
}

Available on crate features esp-now and unstable only.

Common errors that can occur while using ESP-NOW driver.

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

Error(Error)

Internal Error: {0}.

SendFailed

Failed to send an ESP-NOW message.

DuplicateInstance

Attempt to create EspNow instance twice.

Initialization(WifiError)

Initialization error: {0}.

Trait Implementations

impl Clone for EspNowError

fn clone(&self) -> EspNowError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EspNowError

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

Formats the value using the given formatter.

impl Display for EspNowError

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

Formats the value using the given formatter.

impl Error for EspNowError

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 EspNowError

where Error: Format, WifiError: Format,

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

Writes the defmt representation of self to fmt.

impl From<WifiError> for EspNowError

fn from(f: WifiError) -> Self

Converts to this type from the input type.

impl Hash for EspNowError

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 EspNowError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
