Struct Function 

pub struct Function {
    pub args: AstIndex,
    pub local_count: usize,
    pub accessed_non_locals: AstVec<ConstantIndex>,
    pub body: AstIndex,
    pub is_generator: bool,
}

A function definition

Fields

args: AstIndex

The function’s arguments

See Node::FunctionArgs.

local_count: usize

The number of locally assigned values

Used by the compiler when reserving registers for local values at the start of the frame.

accessed_non_locals: AstVec<ConstantIndex>

Any non-local values that are accessed in the function

Any ID (or chain root) that’s accessed in a function and which wasn’t previously assigned locally, is either an export or the value needs to be captured. The compiler takes care of determining if an access is a capture or not at the moment the function is created.

body: AstIndex

The function’s body

is_generator: bool

A flag that indicates if the function is a generator or not

The presence of a yield expression in the function body will set this to true.

Trait Implementations

impl Clone for Function

fn clone(&self) -> Function

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Function

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

Formats the value using the given formatter.

impl PartialEq for Function

fn eq(&self, other: &Function) -> 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 Eq for Function

impl StructuralPartialEq for Function
