Struct AstDiff 

pub struct AstDiff {
    pub changes: Vec<AstChange>,
}

A structured diff between two PEPL ASTs.

Fields

changes: Vec<AstChange>

Implementations

impl AstDiff

pub fn diff(old: &Program, new: &Program) -> Self

Compute the diff between two programs.

pub fn is_empty(&self) -> bool

True if the two ASTs are identical (no changes).

pub fn len(&self) -> usize

Number of changes.

pub fn to_json(&self) -> String

Serialize to compact JSON.

pub fn from_json(json: &str) -> Result<Self, Error>

Deserialize from JSON.

pub fn validate_scope(&self, scope: &AllowedScope) -> Vec<&AstChange>

Validate that all changes fall within allowed scopes. Returns the list of out-of-scope changes (empty = all valid).

Trait Implementations

impl Clone for AstDiff

fn clone(&self) -> AstDiff

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AstDiff

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AstDiff

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AstDiff

fn eq(&self, other: &AstDiff) -> 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 AstDiff

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
