Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotExactlySinglePipe(IVec3)

A block kind requiring one pipe has a different degree.

SpatialPipeNotAllowed(IVec3)

A block kind that accepts only temporal pipes has a spatial pipe.

SpatialPortRoleRequired(IVec3)

A spatial port lacks an explicit input, output, or multiplex role.

TemporalPortRoleMismatch

A temporal port’s declared role disagrees with its pipe direction.

Fields

pos: IVec3

Port position.

declared: PortRole

Explicitly declared role.

inferred: PortRole

Role inferred from the temporal pipe.

FuturePipeNotAllowed(IVec3)

A block accepts only a pipe extending into its past.

PastPipeNotAllowed(IVec3)

A block accepts only a pipe extending into its future.

OrientationContradiction(IVec3, IVec3)

Adjacent block faces imply incompatible lattice-surgery orientations.

JunctionNotPlanar(IVec3)

A multi-pipe junction does not lie in one plane.

DegeneratePipeFace(IVec3, IVec3)

A pipe face has the same basis on both perpendicular axes.

CubeHeightSpatialMismatch

Spatially connected cubes have different symbolic heights.

Fields

pos: IVec3

First cube position.

neighbor: IVec3

Neighboring cube position.

height: CubeHeight

First cube height.

neighbor_height: CubeHeight

Neighboring cube height.

CubeInvalidPipeEndpoint

A pipe attaches to an invalid cell of a multi-cell cube.

Fields

pos: IVec3

Cube anchor position.

endpoint: IVec3

Invalid pipe endpoint.

BlockFootprintOverlap

Two block footprints reserve the same lattice cell.

Fields

pos: IVec3

Multiply occupied lattice cell.

WalkingPipeNotTemporal

A walking block endpoint has a spatial pipe.

Fields

pos: IVec3

Walking-block anchor position.

endpoint: IVec3

Endpoint with the invalid pipe.

WalkingStartPipeNotPast

A walking block’s start endpoint has a non-past pipe.

Fields

pos: IVec3

Walking-block anchor position.

WalkingEndPipeNotFuture

A walking block’s end endpoint has a non-future pipe.

Fields

pos: IVec3

Walking-block anchor position.

PatchRotationEndpointPipeCount

A patch-rotation endpoint does not have exactly one temporal pipe.

Fields

pos: IVec3

Patch-rotation anchor position.

endpoint: IVec3

Endpoint being checked.

count: usize

Number of attached temporal pipes.

PatchRotationPipeNotTemporal

A patch-rotation endpoint has a spatial pipe.

Fields

pos: IVec3

Patch-rotation anchor position.

endpoint: IVec3

Endpoint with the invalid pipe.

PatchRotationStartPipeHadamard

A patch rotation has a Hadamard pipe at its start endpoint.

Fields

pos: IVec3

Patch-rotation anchor position.

PatchRotationBoundaryMismatch

A patch-rotation endpoint has the wrong boundary orientation.

Fields

pos: IVec3

Patch-rotation anchor position.

endpoint: IVec3

Endpoint being checked.

expected: Basis

Boundary basis required by the rotation.

actual: Option<Basis>

Basis inferred from the attached pipe, if any.
