Struct DirectiveKey 

pub struct DirectiveKey {
    pub name: String,
    pub label: String,
    pub attrs: Vec<(String, String)>,
}

What a directive’s reported height is keyed by: everything a host draws it from — its name, its label and its attributes — and nothing about where it stands. The peer of a picture’s destination, which keys crate::Doc::set_media_rows: two directives spelled alike draw alike and so stand as tall, and the height survives an edit above them, which a key by position would not.

An attribute’s value is flattened, a bare attribute to "", because that is the shape both bindings hand a host (DirectiveAttr, a string value) and so the shape a host’s report comes back in; the difference between {wide} and {wide=""} is not one a drawing is expected to make.

Fields

name: String

label: String

attrs: Vec<(String, String)>
