Enum InvalidTagError

#[non_exhaustive]
pub enum InvalidTagError {
    Character(char),
    Empty,
    Length,
}

Error returned when validating an Image Tag.

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.

Character(char)

Tags must only contain ASCII letters (a-z, A-Z), digits (0-9), dots (.), underscores (_), and dashes (-).

Empty

Tag was empty.

Length

Tag was longer than 128 characters.

Trait Implementations

impl Clone for InvalidTagError

fn clone(&self) -> InvalidTagError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for InvalidTagError

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

Formats the value using the given formatter.

impl Display for InvalidTagError

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

Formats the value using the given formatter.

impl Error for InvalidTagError

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 From<InvalidTagError> for InvalidImageError

fn from(source: InvalidTagError) -> Self

Converts to this type from the input type.

impl PartialEq for InvalidTagError

fn eq(&self, other: &InvalidTagError) -> 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.
