Enum Error 

#[non_exhaustive]
pub enum Error {
    EqualsNotFound,
    NameEmpty,
    InvalidName(char),
    InvalidValue(char),
    ExpiresFmt,
    PercentDecodeError,
    InvalidPathValue(char),
    EmptyPathValue,
    NoLeadingSlash,
}

All errors that can be returned while parsing or serializing cookies.

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.

EqualsNotFound

No ‘=’ found in the cookie string.

NameEmpty

Name value is empty.

InvalidName(char)

Name contains invalid character.

InvalidValue(char)

Value contains invalid character.

ExpiresFmt

Unable to format the expires field.

PercentDecodeError

Could not percent-decode the cookie.

InvalidPathValue(char)

Path attribute contains an invalid character.

EmptyPathValue

Path attribute value is empty.

NoLeadingSlash

Path does not start with a leading ‘/’.

Trait Implementations

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

Formats the value using the given formatter.

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
