Struct ArgvSlot 

pub struct ArgvSlot {
    pub fill: FillTemplate,
    pub label: String,
    pub admits_leading_dash: bool,
}

One argv slot: the template that fills it and whether it may begin with a dash.

Fields

fill: FillTemplate

The fill that produces this slot’s element.

label: String

How a refusal names this slot: the first interpolated parameter, or the slot’s literal text.

admits_leading_dash: bool

Whether an element beginning with - is admitted here.

false means the slot’s opening bytes are caller-supplied (its first piece is a hole) and no literal -- element stands before it on the same line, so leading-dash bytes could not be told from an option. The condition is computed from the LINE at compile time and travels here as a fact, never as a keyword an author could write to switch the refusal off.
