Enum HeaderError 

#[non_exhaustive]
pub enum HeaderError {
    Syntax {
        header: &'static str,
    },
    OutOfRange {
        header: &'static str,
    },
    Uri {
        header: &'static str,
        source: UriError,
    },
    UnterminatedQuotedString {
        header: &'static str,
    },
}

A header whose value could not be parsed, or whose value is out of range.

Distinct from a parse error: the message framed correctly and this one header is bad. A proxy may still forward such a message; only a party that needs to read the header has a problem.

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.

Syntax

The value does not match the header’s grammar.

Fields

header: &'static str

The header that failed to parse.

OutOfRange

The value parses but falls outside the range the RFC permits — a CSeq above 2^31-1, a Max-Forwards above 255, a status code outside 100..=699.

Fields

header: &'static str

The header whose value was out of range.

Uri

A URI inside the header did not parse.

Fields

header: &'static str

The header carrying the URI.

source: UriError

Why the URI was rejected.

UnterminatedQuotedString

A quoted string with no closing quote.

Fields

header: &'static str

The header carrying the unterminated string.

Trait Implementations

impl Clone for HeaderError

fn clone(&self) -> HeaderError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HeaderError

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

Formats the value using the given formatter.

impl Display for HeaderError

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

Formats the value using the given formatter.

impl Error for HeaderError

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 HeaderError

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