Struct Capabilities 

pub struct Capabilities<'a> {
    pub uses: &'a [Use],
    pub demands: &'a [Demand],
    pub opens: &'a [&'a str],
}

Everything one application asks of a device.

Fields

uses: &'a [Use]

The services the application uses.

demands: &'a [Demand]

The hardware the application cannot run without.

opens: &'a [&'a str]

The media types of the files the application opens, such as "audio/*" or "application/pdf": the platform then offers it for those files, in a share sheet and in “Open with”, and hands what the person picks to cranpose_services::incoming_share.
