Enum UndoStatus 

#[non_exhaustive]
pub enum UndoStatus {
    Pending,
    Final,
    Canceled,
    Other(String),
}

Whether an EmailSubmission may still be canceled (RFC 8621 §7).

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.

Pending

The message has not yet been relayed; cancellation may be possible.

Final

The message has been relayed to at least one recipient and cannot be recalled.

Canceled

The submission was canceled and will not be delivered to any recipient.

Other(String)

An unrecognised value was received from the server.

The inner string retains the original value so this variant round-trips correctly.

Trait Implementations

impl Clone for UndoStatus

fn clone(&self) -> UndoStatus

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UndoStatus

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for UndoStatus

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for UndoStatus

impl Eq for UndoStatus

impl Hash for UndoStatus

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for UndoStatus

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