Enum HeaderError 

pub enum HeaderError {
    InvalidSyntax,
    Forbidden,
    Immutable,
}

This type enumerates the different kinds of errors that may occur when setting or appending to a fields resource.

Variants

InvalidSyntax

This error indicates that a field-name or field-value was syntactically invalid when used with an operation that sets headers in a fields.

Forbidden

This error indicates that a forbidden field-name was used when trying to set a header in a fields.

Immutable

This error indicates that the operation on the fields was not permitted because the fields are immutable.

Trait Implementations

impl Clone for HeaderError

fn clone(&self) -> HeaderError

Returns a duplicate 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<(), Error>

Formats the value using the given formatter.

impl Display for HeaderError

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

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

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.
