Enum ChangeType 

pub enum ChangeType {
    Added,
    Removed,
    Modified,
    Renamed,
    SignatureChanged,
    Unchanged,
}

Kind of change detected between the two snapshots.

Variants

Added

Node is present in the new snapshot but not the old.

Removed

Node is present in the old snapshot but not the new.

Modified

Node exists on both sides but its body / location changed while the signature stayed identical.

Renamed

Node was matched heuristically as a renamed version of a node that disappeared (>= 90% confidence via signature + location scoring).

SignatureChanged

Node exists on both sides and its signature changed.

Unchanged

Node exists unchanged on both sides. Callers opt into emitting these via their own filter logic — compute_diff never emits this variant directly.

Implementations

impl ChangeType

pub fn as_str(&self) -> &'static str

Returns the stable wire-format string for this change type. The mapping matches the pre-DB20 MCP and CLI outputs exactly.

Trait Implementations

impl Clone for ChangeType

fn clone(&self) -> ChangeType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChangeType

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

Formats the value using the given formatter.

impl Hash for ChangeType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ChangeType

fn eq(&self, other: &ChangeType) -> 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.
