Enum MessageError 

#[non_exhaustive]
pub enum MessageError {
    Json(Error),
    UnsupportedVersion(u8),
    EmptyQuery,
    MaxResultsOutOfRange(u32),
}

Errors that can occur when encoding or decoding a NERVE message payload.

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.

Json(Error)

The JSON payload could not be serialized or deserialized.

UnsupportedVersion(u8)

The v field in the payload does not equal MESSAGE_VERSION.

EmptyQuery

The query field is an empty string.

MaxResultsOutOfRange(u32)

The max_results field is outside 1..=MAX_RESULTS.

Trait Implementations

impl Debug for MessageError

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

Formats the value using the given formatter.

impl Display for MessageError

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

Formats the value using the given formatter.

impl Error for MessageError

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<Error> for MessageError

fn from(e: Error) -> Self

Converts to this type from the input type.
