Enum TextPurpose 

pub enum TextPurpose {
    Normal,
    Password,
    Pin,
}

What a text field taking typing is for, as an input method needs to know it.

Here rather than in crcbl-shell for the reason CursorIcon is: a UI names it for its field, and a UI crate depends on this one, not on the shell.

Exhaustive on purpose, as CursorIcon is: a purpose added later must fail to compile in every backend’s mapping rather than fall to Normal through a wildcard arm, because a password read as ordinary text is one an input method may learn and suggest back.

Variants

Normal

Ordinary text: the input method may complete, correct and remember.

Password

A password: hidden as typed, and nothing typed may be stored, learned or offered back as a suggestion.

Pin

A PIN: digits, hidden, and not stored, as a password.
