Struct ObjectShape 

pub struct ObjectShape {
    pub flags: ObjectFlags,
    pub properties: Vec<PropertyInfo>,
    pub string_index: Option<IndexSignature>,
    pub number_index: Option<IndexSignature>,
    pub symbol: Option<SymbolId>,
}

Object type with properties and optional index signatures

NOTE: The symbol field affects BOTH Hash and PartialEq for nominal discrimination. This ensures that different classes get different TypeIds in the interner. Structural subtyping is computed explicitly in the Solver, not via PartialEq.

Fields

flags: ObjectFlags

Object-level flags (e.g. fresh literal tracking).

properties: Vec<PropertyInfo>

Named properties (sorted by name for consistent hashing)

string_index: Option<IndexSignature>

String index signature: { [key: string]: T }

number_index: Option<IndexSignature>

Number index signature: { [key: number]: T }

symbol: Option<SymbolId>

Nominal identity for class instance types (prevents structural interning of distinct classes)

Trait Implementations

impl Clone for ObjectShape

fn clone(&self) -> ObjectShape

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObjectShape

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

Formats the value using the given formatter.

impl Default for ObjectShape

fn default() -> Self

Returns the “default value” for a type.

impl Hash for ObjectShape

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 ObjectShape

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