Module diff 

Structural diffing of two schemas.

diff compares an old and new schema, producing a SchemaDiff that records every added, removed, or modified element. The diff is purely structural; it does not yet classify changes as breaking or non-breaking (that is handled by crate::classify()).

Structs

ConstraintChange

A single constraint that changed its value.

ConstraintDiff

Describes how constraints on a single vertex changed.

HyperEdgeChange

Records changes to a hyper-edge’s kind, signature, or parent label.

KindChange

Records a vertex whose kind changed between schema versions.

RecursionPointChange

Records a recursion point whose target vertex changed.

SchemaDiff

A structural diff between two schemas.

SpanChange

Records a span whose left or right vertex changed.

VariantChange

Records a variant whose tag changed between schema versions.

Functions

apply_renames

Rewrite a SchemaDiff to recognise vertex renames.

diff

Compute a structural diff between two schemas.
