Struct Head 

pub struct Head {
    pub format: u32,
    pub locale: Option<String>,
    pub options: Options,
}

What a bundle says about itself, apart from the installation it carries.

A head that has been read is in BUNDLE_FORMAT, since any other is refused; the field is kept because a head is also what gets written.

Fields

format: u32

locale: Option<String>

The language the options are written in: a plain string is in it, and a translated one must hold it, so a launcher always has something to fall back to. Needed only once some text is translated.

options: Options

What whoever launches the bundle may choose: the variables and features it leaves to them, and how to ask for each.

Implementations

impl Head

pub fn new(locale: Option<String>, options: Options) -> Result<Self, String>

A head in the format this crate writes. Refuses a locale that is no language tag, and a translated text with no locale or without it.
