フレームデコードエラー

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.

BufferTooShort

バッファ不足

UnknownFrameType(u64)

不明なフレームタイプ

InvalidLength

無効なフレーム長

InvalidSetting(SettingError)

SETTINGS パラメータの構築時検査でエラーが発生した

内部に SettingError を保持し、ID / 値 / 重複の詳細を伝える (RFC 9114 §7.2.4 / §7.2.4.1)。

Http2Frame(VarInt)

HTTP/2 専用フレームの検出

ServerPushNotSupported(VarInt)

サーバープッシュはサポートしない (CANCEL_PUSH, PUSH_PROMISE, MAX_PUSH_ID)

Trait Implementations

impl Clone for FrameDecodeError

fn clone(&self) -> FrameDecodeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FrameDecodeError

impl Debug for FrameDecodeError

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

Formats the value using the given formatter.

impl Display for FrameDecodeError

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

Formats the value using the given formatter.

impl Eq for FrameDecodeError

impl Error for FrameDecodeError

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<FrameDecodeError> for Error

fn from(e: FrameDecodeError) -> Self

Converts to this type from the input type.

impl From<SettingError> for FrameDecodeError

fn from(e: SettingError) -> Self

Converts to this type from the input type.

impl PartialEq for FrameDecodeError

fn eq(&self, other: &FrameDecodeError) -> 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.
