Struct CallableShape 

pub struct CallableShape {
    pub call_signatures: Vec<CallSignature>,
    pub construct_signatures: Vec<CallSignature>,
    pub properties: Vec<PropertyInfo>,
    pub string_index: Option<IndexSignature>,
    pub number_index: Option<IndexSignature>,
    pub symbol: Option<SymbolId>,
}

Callable type with multiple overloaded call signatures Represents types like:

interface Overloaded {
  (x: string): number;
  (x: number): string;
}

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

call_signatures: Vec<CallSignature>

Call signatures (order matters for overload resolution)

construct_signatures: Vec<CallSignature>

Constructor signatures

properties: Vec<PropertyInfo>

Optional properties on the callable (e.g., Function.prototype)

string_index: Option<IndexSignature>

String index signature (for static index signatures on classes)

number_index: Option<IndexSignature>

Number index signature (for static index signatures on classes)

symbol: Option<SymbolId>

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

Trait Implementations

impl Clone for CallableShape

fn clone(&self) -> CallableShape

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CallableShape

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

Formats the value using the given formatter.

impl Default for CallableShape

fn default() -> CallableShape

Returns the “default value” for a type.

impl Hash for CallableShape

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 CallableShape

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.
