pub struct HeaderError { /* fields omitted */ }

Errors due the fact that the header rule is not respected.

Implementations

impl HeaderError

pub fn kind(&self) -> HeaderErrorKind

Returns the general category of this error.

pub fn downcast_ref<E>(&self) -> Option<&E> where
    E: Display + Debug + Send + Sync + 'static, 

Downcast this error object by reference.

pub fn root_cause(&self) -> &(dyn Error + 'static)

The lowest level cause of this error — this error’s cause’s cause’s cause etc.

pub fn cause(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

Trait Implementations

impl Clone for HeaderError

fn clone(&self) -> HeaderError

Returns a copy 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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for HeaderError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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
