Struct Layout 

pub struct Layout { /* private fields */ }

Implementations

impl Layout

pub fn empty(own_id: MachineId) -> Self

pub fn version(&self) -> u64

pub fn by(&self) -> MachineId

pub fn placements(&self) -> &[Placement]

pub fn nth( &self, n: u8, eligible: impl Fn(MachineId) -> bool, ) -> Option<MachineId>

One-based machine number, ordered top to bottom, then left to right. Ineligible placements keep their numbers but cannot be selected.

pub fn edit( &self, placements: Vec<Placement>, own_id: MachineId, ) -> Result<Self, LayoutError>

Errors

Rejects invalid placements and an exhausted version counter.

pub fn merge(&mut self, incoming: Self, own_id: MachineId) -> Merge

pub fn to_proto(&self) -> Layout

pub fn exit( &self, from: MachineId, edge: Edge, along: f32, eligible: impl Fn(MachineId) -> bool, ) -> Option<(MachineId, Landing)>

Map an exit to an eligible touching machine’s opposite edge and fractional offset.

pub fn exit_corner( &self, from: MachineId, edge: Edge, corner: Corner, eligible: impl Fn(MachineId) -> bool, ) -> Option<(MachineId, Landing)>

Map a diagonal push to a neighbour touching only at the given corner. Call after exit so a shared edge takes precedence.
