Crate draxl_patch 

Structured patch operations over the Draxl semantic model.

The patch layer applies semantic edit operators directly to the Draxl AST. It is intentionally slot-aware, identity-aware, and attachment-aware so callers can express concurrent-friendly structural edits instead of rewriting text.

Structs

PatchError

Error produced while applying a patch operation.

PatchPath

Path address for scalar field or metadata updates.

PatchTextError

Error produced while parsing, resolving, or applying textual patch ops.

RankedDest

Ranked destination for ordered slots.

SlotRef

Public slot reference in the Draxl patch surface.

SurfaceFragment

Fragment source carried verbatim until schema resolution picks a parser.

SurfaceNodeRef

Parsed @id node reference.

SurfacePath

Parsed scalar path before schema resolution.

SurfacePathSegment

Parsed scalar path segment.

SurfaceRankedDest

Parsed ranked destination before schema resolution.

SurfaceSlotRef

Parsed slot reference before schema resolution.

SurfaceValue

Parsed scalar value before type resolution.

Enums

PatchDest

Destination grammar shared by insert and move.

PatchNode

Replaceable, movable, or insertable semantic fragment.

PatchOp

Structured patch operation over the Draxl semantic model.

PatchValue

Scalar value used by set.

SlotOwner

Slot owner used by slot refs and destinations.

SurfaceDest

Parsed move destination before schema resolution.

SurfacePatchOp

Unresolved textual patch op parsed from the canonical patch surface.

SurfaceSlotOwner

Parsed owner for a slot ref.

SurfaceValueKind

Surface scalar value variants.
