Struct MapConnections 

#[non_exhaustive]
pub struct MapConnections<M: MapTrait> {
    pub north: Option<MapConnection<M>>,
    pub south: Option<MapConnection<M>>,
    pub west: Option<MapConnection<M>>,
    pub east: Option<MapConnection<M>>,
}

All connections for a map (up to one per cardinal direction).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

north: Option<MapConnection<M>>

south: Option<MapConnection<M>>

west: Option<MapConnection<M>>

east: Option<MapConnection<M>>

Implementations

impl<M: MapTrait> MapConnections<M>
