Enum Error 

#[non_exhaustive]
pub enum Error {
    InvalidHeader {
        name: HeaderName,
    },
    DuplicateHeader {
        name: HeaderName,
    },
    UnsupportedHeaderName {
        name: String,
    },
}

An error produced while extracting request metadata.

The public taxonomy is intentionally small. Parser details, header values, and credentials are absent from every variant, so formatting an error cannot disclose request secrets.

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.

InvalidHeader

A field is malformed or cannot be decoded; its value is omitted.

Fields

name: HeaderName

The malformed field name.

DuplicateHeader

A field defined by an extractor as singular occurred more than once.

Fields

name: HeaderName

The duplicated field name.

UnsupportedHeaderName

A configured Header name is unsupported by the selected operation.

Fields

name: String

The unsupported field name.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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 Error

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

Equality operator ==.

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

Inequality operator !=.
