Enum CodecError 

pub enum CodecError {
    Decode(String),
    Encode(String),
    PayloadSizeMismatch,
    UnknownEnumValue(u32),
}

Unified codec error type used by every codec in the stack.

GTP, GAP and GSP all return this error so that callers can handle decoding failures uniformly without having to know which sub-protocol was being parsed.

Variants

Decode(String)

CBOR decoding failure.

Encode(String)

CBOR encoding failure (practically unreachable when writing to a Vec).

PayloadSizeMismatch

A length field inside the frame does not match the actual payload length (payload_size, content_length, args_length, …).

UnknownEnumValue(u32)

An unknown enum value was observed (for example an out-of-range stream_type or signal_type).

Trait Implementations

impl Debug for CodecError

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

Formats the value using the given formatter.

impl Display for CodecError

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

Formats the value using the given formatter.

impl Error for CodecError

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.
