Struct SmtpReplyCode 

pub struct SmtpReplyCode {
    pub class: u8,
    pub subject: u8,
    pub detail: u8,
}

A 3-digit SMTP reply code.

Each digit carries independent meaning: class (1st digit) signals the broad outcome, subject (2nd digit) and detail (3rd digit) refine it.

Fields

class: u8

First digit: 2 (positive completion), 3 (positive intermediate), 4 (transient negative), or 5 (permanent negative).

subject: u8

Second digit: 0–9.

detail: u8

Third digit: 0–9.
