Struct Shapes 

pub struct Shapes { /* private fields */ }

The rules, in the order the caller gave them.

Empty is the ordinary state and means Shape::Auto for everything, which is what every export did before there was anything to ask.

Implementations

impl Shapes

pub fn new() -> Self

No rules: every object in its natural shape.

pub fn with(self, selector: Selector, shape: Shape) -> Self

Add a rule at the end, where it will be tried last.

pub fn parse_rule(self, rule: &str) -> Result<Self, String>

Parse one PATTERN=SHAPE rule and add it.

The error says which half was not understood and what the alternatives are, because this is typed on a command line by someone who will not go looking for documentation to find out that polygon was spelled polygons.

pub fn shape_for(&self, qualified_type: &str) -> Shape

The shape asked for this qualified type: the first rule that matches, or Shape::Auto.

pub fn is_empty(&self) -> bool

Whether any rule was given at all.

pub fn rules(&self) -> &[(Selector, Shape)]

The rules, for a caller echoing them back.
