Struct TipRules 

pub struct TipRules<'a> {
    pub limits: TipLimits,
    pub widths: &'a CellWidths,
    pub placeholder: &'a dyn Fn(&str) -> bool,
    pub face_problem: &'a dyn Fn(&str) -> Option<String>,
    pub default_face: &'a str,
}

What from_source checks tips against besides their box: which placeholders exist, and what is wrong with a tip’s face.

Fields

limits: TipLimits

How much text the box holds.

widths: &'a CellWidths

How many cells each character takes, which the limits count: the font atlas’s (CellWidths::of), or CellWidths::NARROW.

placeholder: &'a dyn Fn(&str) -> bool

Whether {name} is a placeholder the game fills in.

face_problem: &'a dyn Fn(&str) -> Option<String>

What is wrong with a tip showing the face face (its own, or the game’s default), if anything.

default_face: &'a str

The face of a tip that names none.
