Struct SchemaDiff 

pub struct SchemaDiff {
    pub adds: Vec<DiffEntry>,
    pub removes: Vec<DiffEntry>,
    pub breaking: Vec<DiffEntry>,
}

Structured diff between two schemas.

Iteration order of each field is deterministic (BTreeMap-backed internally), so the serialised JSON is suitable for snapshot tests and CI attestation.

Fields

adds: Vec<DiffEntry>

Additive-only changes: new labels, rels, parameters, and optional properties.

removes: Vec<DiffEntry>

Removals of previously-declared items.

breaking: Vec<DiffEntry>

Changes that are structurally backwards-incompatible.

Implementations

impl SchemaDiff

pub fn is_empty(&self) -> bool

true iff every bucket is empty — the two schemas are semantically equal.

pub fn has_breaking(&self) -> bool

true iff there is at least one breaking change.

Trait Implementations

impl Clone for SchemaDiff

fn clone(&self) -> SchemaDiff

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SchemaDiff

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SchemaDiff

fn default() -> SchemaDiff

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SchemaDiff

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SchemaDiff

fn eq(&self, other: &SchemaDiff) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for SchemaDiff

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
