Struct FrontierMenu 

Source 
pub struct FrontierMenu {
    pub slots: Vec<(String, Expr)>,
    pub heads: Expr,
    pub head_shape: Arc<dyn Shape>,
    pub grammar: String,
}
Expand description

Legal next heads plus in-scope slot shapes for a BRIDGE packet.

Fields§

§slots: Vec<(String, Expr)>

Slot id to shape descriptor.

§heads: Expr

§head_shape: Arc<dyn Shape>

Shape object backing the legal next move heads.

§grammar: String

Grammar lowered from the same flat OneOf.
