Enum EnvelopeError 

pub enum EnvelopeError {
    Compatibility(CompatibilityError),
    NotAnObject,
    MissingVersion,
    InvalidVersion(String),
    MissingPayload,
    Json(Error),
    Payload(Error),
}

Errors from envelope JSON decode, including compatibility failures.

Variants

Compatibility(CompatibilityError)

Version is outside the supported window.

NotAnObject

Top-level JSON was not an object.

MissingVersion

Envelope object lacked wire_version.

InvalidVersion(String)

wire_version was present but not a u32.

MissingPayload

Envelope object lacked payload after the version check passed.

Json(Error)

Failed to parse or serialize envelope JSON.

Payload(Error)

Version was supported, but the payload did not decode as T.

Trait Implementations

impl Debug for EnvelopeError

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

Formats the value using the given formatter.

impl Display for EnvelopeError

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

Formats the value using the given formatter.

impl Error for EnvelopeError

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<CompatibilityError> for EnvelopeError

fn from(source: CompatibilityError) -> Self

impl From<EnvelopeError> for ZmqMessageError

fn from(source: EnvelopeError) -> Self
