source · [−]

pub struct HeaderError { /* private fields */ }

Expand description

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.
