Enum FrameError 

pub enum FrameError {
    LengthTruncated,
    LengthTooLarge(u32),
    BodyTruncated {
        expected: u32,
        actual: usize,
    },
    DecodeFailed,
    Io(Error),
}

Errors emitted by the framing layer. Wire-protocol errors (a frame longer than MAX_FRAME_BYTES, a truncated read) are distinct from decode errors so callers can decide whether to close the connection or just surface a parse failure.

Variants

LengthTruncated

The 4-byte length prefix could not be read in full.

LengthTooLarge(u32)

The advertised length exceeded MAX_FRAME_BYTES. Receivers MUST close the connection rather than continue reading.

BodyTruncated

The frame body could not be read in full (peer closed, IO error, etc.).

Fields

expected: u32

actual: usize

DecodeFailed

The frame body did not decode as the expected message type.

Io(Error)

Underlying IO error.

Trait Implementations

impl Debug for FrameError

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

Formats the value using the given formatter.

impl Display for FrameError

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

Formats the value using the given formatter.

impl Error for FrameError

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 FrameError

fn from(source: Error) -> Self

Converts to this type from the input type.
