Struct FunctionDef 

pub struct FunctionDef {
    pub name: String,
    pub entry: u32,
    pub arity: u8,
    pub num_registers: u8,
}

A callable entry point inside a Chunk: either bytecode-defined or a slot reserved for a native (Rust) function registered with the runtime via the FFI table (design notes §30-31).

Fields

name: String

entry: u32

Index into Chunk::code where execution starts.

arity: u8

Number of parameters, passed in registers r0..r{arity}.

num_registers: u8

Upper bound on registers this function uses; the VM allocates exactly this many per call frame instead of a fixed worst-case size.
