JavascriptFunction

Struct JavascriptFunction 

Source
pub struct JavascriptFunction {
    pub private_names: Vec<String>,
    /* private fields */
}
Expand description

Inspectable callable metadata. Shared plans and capture cells own neutral mechanics; this record retains only JavaScript and object-system policy.

Fields§

§private_names: Vec<String>

Declared private names for a class constructor.

Implementations§

Source§

impl JavascriptFunction

Source

pub fn new( plan: FunctionPlan, captures: Vec<CapturedBinding>, policy: JavascriptFunctionPolicy, private_names: Vec<String>, ) -> Result<Self, InstanceError>

Freezes a JavaScript function over an already validated neutral plan.

Source

pub const fn plan(&self) -> &FunctionPlan

Borrows the shared immutable declaration plan.

Source

pub fn captures(&self) -> &[CapturedBinding]

Borrows exact capture cells in frozen plan order.

Source

pub const fn policy(&self) -> &JavascriptFunctionPolicy

Borrows JavaScript-only callable policy.

Source

pub fn bind_arguments( &self, arguments: &[JavascriptValue], ) -> Result<BTreeMap<Symbol, Vec<JavascriptValue>>, JavascriptCallError>

Applies ECMAScript positional, default, and rest rules to raw values.
