Struct FunctionPrototype 

pub struct FunctionPrototype {
    pub name: Option<String>,
    pub async_function: bool,
    pub arity: u16,
    pub variadic: bool,
    pub capture_count: u16,
    pub local_count: u16,
    pub max_stack: u16,
    pub code: Vec<Instruction>,
    pub source_map: SourceMap,
    pub handlers: Vec<TryEntry>,
}

A compiled function. The entry function has arity and capture count 0; fn/defn forms contribute the remaining prototypes.

Fields

name: Option<String>

async_function: bool

Calling this prototype creates a child async execution and returns its stable result promise instead of the direct body value.

arity: u16

Required argument count. Always 0 for the entry function. When variadic is set this counts only the fixed parameters.

variadic: bool

Whether the last parameter binds the remaining arguments as a Value::List ([a b & rest]).

capture_count: u16

Number of captured values the frame expects in the slots directly above the parameters. Always 0 for the entry function.

local_count: u16

Number of local slots the frame allocates.

max_stack: u16

Declared operand-stack high-water mark; the validator recomputes and verifies it.

code: Vec<Instruction>

source_map: SourceMap

handlers: Vec<TryEntry>

Static handler table for try/catch/finally; empty for functions without protected regions.

Trait Implementations

impl Clone for FunctionPrototype

fn clone(&self) -> FunctionPrototype

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionPrototype

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

Formats the value using the given formatter.
