Struct SettingKind 

pub struct SettingKind(/* private fields */);

What an optional key may hold, for Schema::optional: the same kinds as the builders with a default (Schema::flag, Schema::text, Schema::choice, Schema::check), without the default.

A plain value rather than one builder per kind (optional_flag, optional_text, …): the kinds stay listed once, and any kind can be optional.

use qframe::storage::{Schema, SettingKind};

let schema = Schema::builtin()
    .optional("deploy.note", SettingKind::text())
    .optional("deploy.retries", SettingKind::check(|retries: &u8| (1..=10).contains(retries)));
