HPACK ヘッダーフィールド構築時検査エラー

RFC 9113 §8.2 / §8.3 および RFC 9110 §5 で定義される field-name / field-value / 疑似ヘッダーの構文制約を、構築点で検出した結果を表現する。

Vec<u8> フィールドを持つため Copy は導出不可能。

Variants

EmptyFieldName

field-name が空

RFC 9110 §5.1, §5.6.2: token = 1*tchar

UppercaseFieldName

field-name に lowercase 以外の ASCII 英字が含まれる

RFC 9113 §8.2.1: MUST NOT contain 0x41-0x5a (uppercase ASCII)

Fields

name: Vec<u8>

違反した field-name

InvalidFieldNameByte

field-name に token 文字以外が含まれる

RFC 9110 §5.1, §5.6.2 / RFC 9113 §8.2.1

Fields

name: Vec<u8>

違反した field-name

byte: u8

違反したバイト値

InvalidFieldValueByte

field-value に NUL/CR/LF が含まれる

RFC 9113 §8.2.1: MUST NOT contain 0x00, 0x0a, 0x0d

Fields

name: Vec<u8>

違反した field-name (デバッグ補助)

byte: u8

違反したバイト値

FieldValueLeadingOrTrailingWhitespace

field-value が先頭または末尾に SP/HTAB を含む

RFC 9113 §8.2.1: MUST NOT start or end with 0x20 (SP) or 0x09 (HTAB)

Fields

name: Vec<u8>

違反した field-name (デバッグ補助)

UnknownPseudoHeader

疑似ヘッダー名が未定義 (:foo のような不明な疑似ヘッダー)

RFC 9113 §8.3 / RFC 8441 §4: 定義済み疑似ヘッダーのみ許可

Fields

name: Vec<u8>

違反した field-name

InvalidPseudoHeaderValue

疑似ヘッダー値が構文違反

各疑似ヘッダーの構文根拠:

• :method: RFC 9110 §9.1 (token)
• :scheme: RFC 3986 §3.1 (scheme)
• :path: RFC 9113 §8.3.1, RFC 9110 §4.1 (absolute-path)
• :status: RFC 9112 §4, RFC 9110 §15 (3DIGIT)
• :protocol: RFC 8441 §4 (HTTP Upgrade Token)
• :authority: RFC 3986 §3.2 (authority)

Fields

name: Vec<u8>

Trait Implementations

impl Clone for HeaderFieldError

fn clone(&self) -> HeaderFieldError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HeaderFieldError

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

Formats the value using the given formatter.

impl Display for HeaderFieldError

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

Formats the value using the given formatter.

impl Eq for HeaderFieldError

impl Error for HeaderFieldError

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<HeaderFieldError> for ValidationError

fn from(e: HeaderFieldError) -> Self

Converts to this type from the input type.

impl Hash for HeaderFieldError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for HeaderFieldError

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