Struct HeaderError

pub struct HeaderError { /* private fields */ }

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)>

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
