Struct Draft 

pub struct Draft {
    pub tag: String,
    pub kind: ProviderKind,
    pub base: String,
    pub key: String,
    pub problem: Option<Problem>,
}

A provider being written down.

Fields

tag: String

The tag as it has been typed.

kind: ProviderKind

Which kind it is.

base: String

The address as it has been typed.

key: String

The key as it is being typed. Never shown back: the field it lives in is a password field, and once the provider is added this is gone.

problem: Option<Problem>

What stopped it last time the person asked for it to be added, or nothing while they have not asked yet. A form does not complain about a field nobody has finished.

Implementations

impl Draft

pub fn new() -> Self

A new form, on the kind the page offers first, with that kind’s usual address already in the field so the common case is one word of typing.

pub fn pick_kind(&mut self, kind: ProviderKind)

Chooses a kind, and moves the address along with it when the person has not changed the one that was offered. A person who typed their own address keeps it. A ready-made kind brings its own tag too, on the same terms: only into a field the person has not written.

pub fn pick_region(&mut self, index: usize)

Chooses where a ready-made provider answers, the indexth of its kind’s regions. The address is the region’s whatever was in the field: picking a region is saying which address, and nothing else does that.

pub fn region(&self) -> Option<usize>

Which of the kind’s regions the address is, or None when the person wrote one of their own.

pub fn build( &self, taken: impl Fn(&str) -> bool, ) -> Result<ProviderEntry, Problem>

The provider this form describes, or the first reason it is not one.

taken says whether a tag is already in the list, which only the list knows.

Errors

Problem says what stopped it and which field it belongs beside.
