Enum WriteError 

#[non_exhaustive]
pub enum WriteError {
    OutOfSequence,
    OutOfSpace,
}

Error type for manipulation of MessageMut mutable messages.

This is presented externally as an internal server error, but has enough structure to be useful for debugging through dbg!().

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.

Trait Implementations

impl Debug for WriteError

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

Formats the value using the given formatter.

impl Display for WriteError

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

Formats the value using the given formatter.

impl Error for WriteError

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 WriteError

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

Writes the defmt representation of self to fmt.

impl From<Infallible> for WriteError

fn from(never: Infallible) -> Self

Converts to this type from the input type.

impl RenderableOnMinimal for WriteError

type Error<IE: RenderableOnMinimal + Debug> = IE

Error to return when even the error rendering is unsuccessful (a “double error”).

fn render<M: MinimalWritableMessage>( self, msg: &mut M, ) -> Result<(), Self::Error<M::UnionError>>

Express the error in a CoAP response message
