Enum Action 

#[non_exhaustive]
pub enum Action {
    Shutdown,
    Echo(String),
    Continue,
}

Msg content type can also be Command. Action represents tasks corresponding to Commands.

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.

Shutdown

Shutdown the message listener

Echo(String)

Send an echo message to the listener

Continue

Good to go, carry on

Implementations

impl Action

pub fn inner(&self) -> &str

Inner content such as echo message

pub fn execute(&mut self, _input: Mail) -> Option<Mail>

Execute the action embedded in a Mail whose content might be a Command For echo action execute just reverses the incoming text

Trait Implementations

impl Clone for Action

fn clone(&self) -> Action

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Action

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Action

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Action

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

Formats the value using the given formatter.

impl PartialEq for Action

fn eq(&self, other: &Action) -> 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 Action

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
