Struct CoapError 

pub struct CoapError {
    pub code: Option<ResponseType>,
    pub message: String,
}

Error type which can be converted to a crate::app::Response as a convenience for allowing Rust’s ? operator to work naturally in handler code without violating the protocol by failing to respond to requests.

Fields

code: Option<ResponseType>

message: String

Trait Implementations

impl Clone for CoapError

fn clone(&self) -> CoapError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CoapError

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

Formats the value using the given formatter.

impl Display for CoapError

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

Formats the value using the given formatter.

impl Error for CoapError

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<HandlingError> for CoapError

fn from(src: HandlingError) -> Self

Converts to this type from the input type.
