Implementations

impl Mail

pub fn message(&self) -> &Msg

Get a handle to the inner message

pub fn messages(&self) -> &Vec<Msg>

Get a handle to inner messages without hollowing out the mail

pub fn take(self) -> Msg

Take the inner message out - if its a Trade variant

pub fn take_all(self) -> Vec<Msg>

Take all the content out if its Mail enum variant is Bulk

pub fn command_equals(&self, action: Action) -> bool

If the mail is actually a command - does it match a specific command

pub fn is_command(&self) -> bool

Is the mail is actually a containing a single command like Shutdown etc?

pub fn action(&self) -> Option<Action>

Get the embedded Action out if this mail is a command

pub fn is_blank(mail: &Mail) -> bool

Is the mail empty - mostly to avoid transmitting

pub fn set_from(mail: &mut Option<Mail>, from: &Addr)

Set from address on all the messagess inside a potential mail
