Enum EmailEncryption 

pub enum EmailEncryption {
    Auto,
    Tls,
    Starttls,
    None,
}

Email transport encryption mode.

Variants

Auto

Pick based on port: 465 → SMTPS, 25 → none, otherwise STARTTLS.

Tls

Implicit TLS on connect (typically port 465).

Starttls

Plain SMTP that upgrades to TLS via STARTTLS (typically port 587).

None

Plain SMTP, no TLS. Only safe on trusted local relays (port 25).

Trait Implementations

impl Clone for EmailEncryption

fn clone(&self) -> EmailEncryption

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EmailEncryption

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

Formats the value using the given formatter.

impl Default for EmailEncryption

fn default() -> EmailEncryption

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for EmailEncryption

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for EmailEncryption

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq for EmailEncryption

fn eq(&self, other: &EmailEncryption) -> 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 Serialize for EmailEncryption

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
