Enum HeaderSyntaxError 

#[non_exhaustive]
pub enum HeaderSyntaxError {
    MissingColon,
    EmptyName,
    NameNotToken,
    BareNewline,
    LeadingFold,
}

What was wrong with a header field line.

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.

MissingColon

No colon separating name from value.

EmptyName

The field name is empty.

NameNotToken

The field name contains a character outside the token set.

BareNewline

A bare CR or LF where a CRLF was required.

sipx never accepts a bare LF as a line terminator: two elements disagreeing about where a message ends is how a body becomes a second request.

LeadingFold

The first line of the header section begins with whitespace, so it continues a header that does not exist.

Trait Implementations

impl Clone for HeaderSyntaxError

fn clone(&self) -> HeaderSyntaxError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HeaderSyntaxError

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

Formats the value using the given formatter.

impl Display for HeaderSyntaxError

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

Formats the value using the given formatter.

impl Error for HeaderSyntaxError

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 HeaderSyntaxError

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