Enum ReversePath 

#[non_exhaustive]
pub enum ReversePath {
    Null,
    Mailbox(Mailbox),
}

A validated SMTP reverse-path for MAIL FROM.

RFC 5321 Section 4.1.1.2: Reverse-path = Path / "<>". A null reverse-path (<>) indicates a bounce message. Obsolete source routes in Path syntax are accepted but ignored per RFC 5321 Section 4.1.2.

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.

Null

Null reverse-path (<>) — bounce/DSN message.

Mailbox(Mailbox)

A mailbox address.

Implementations

impl ReversePath

pub fn new(s: impl Into<String>) -> Result<Self, ValidationError>

Create from a string. An empty string produces Null.

pub fn as_str(&self) -> &str

Return the path as a string slice (empty for null path).

pub fn requires_smtputf8(&self) -> bool

Returns true if this is a non-null path with non-ASCII characters, requiring the SMTPUTF8 extension (RFC 6531 Sections 3.3-3.4).

Trait Implementations

impl Clone for ReversePath

fn clone(&self) -> ReversePath

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReversePath

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

Formats the value using the given formatter.

impl Display for ReversePath

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

Formats the value using the given formatter.

impl Hash for ReversePath

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 ReversePath

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

impl TryFrom<&str> for ReversePath

type Error = ValidationError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<Self, ValidationError>

Performs the conversion.

impl TryFrom<String> for ReversePath

type Error = ValidationError

The type returned in the event of a conversion error.

fn try_from(s: String) -> Result<Self, ValidationError>

Performs the conversion.
