Why a header could not be decoded.

Variants

TooShortForPrefix

Fewer than FROZEN_PREFIX_LEN bytes — cannot even read len/ver.

Fields

have: usize

UnsupportedVersion

ver is not a version this build understands.

Fields

ver: u8

TooShortForHeader

Version known but fewer than its header length is present.

Fields

have: usize

need: usize

UnknownFrameType

type byte is not a known FrameType.

Fields

byte: u8

ReservedFlagBits

A reserved flag bit (4-7) is set.

Fields

flags: u8

ReservedPriorityBits

Priority bits 1-2 hold the reserved value 0b11.

Fields

flags: u8

PureHeaderFrameWithBody

A pure-header frame declared body bytes.

Fields

ty: FrameType

len: u32

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> DecodeError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for DecodeError

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Eq for DecodeError

impl Error for DecodeError

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 PartialEq for DecodeError

fn eq(&self, other: &DecodeError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
