Enum vsmtp_protocol::ConnectionKind

#[non_exhaustive]
pub enum ConnectionKind {
    Relay,
    Submission,
    Tunneled,
}

Type of SMTP connection.

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.

Submission

Connection coming for submission (MSA on port 587) see https://datatracker.ietf.org/doc/html/rfc6409

Tunneled

Connection coming for submissionS (MSA on port 465) see https://datatracker.ietf.org/doc/html/rfc8314

Trait Implementations

impl Clone for ConnectionKind

fn clone(&self) -> ConnectionKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConnectionKind

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

Formats the value using the given formatter.

impl Default for ConnectionKind

fn default() -> ConnectionKind

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ConnectionKindwhere Self: FromStr, <Self as FromStr>::Err: Display,

fn deserialize<__D>(deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ConnectionKind

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

Formats the value using the given formatter.

impl FromStr for ConnectionKind

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<ConnectionKind, <Self as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for ConnectionKind

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<ConnectionKind> for ConnectionKind

fn eq(&self, other: &ConnectionKind) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for ConnectionKindwhere Self: Display,

fn serialize<__S>(&self, serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&str> for ConnectionKind

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<ConnectionKind, <Self as TryFrom<&str>>::Error>

Performs the conversion.
