Struct Binding 

pub struct Binding { /* private fields */ }

The result of ParamList::bind: what each parameter receives, and the presence mask.

Examples

use bytecode_lang::{ArgItem, Bound, ModuleBuilder, Param, ParamKind, ParamList};

let module = ModuleBuilder::new().finish().unwrap();
let list = ParamList::new(vec![Param::new(ParamKind::PositionalOnly, None)]);
let b = list.bind(&module, &[ArgItem::Positional]).unwrap();
assert_eq!(b.slots(), &[Bound::Arg(0)]);
assert_eq!(b.presence(), 1);

Implementations

impl Binding

pub fn slots(&self) -> &[Bound]

What each parameter receives, in parameter order.

Examples

use bytecode_lang::{ModuleBuilder, ParamList};

let module = ModuleBuilder::new().finish().unwrap();
assert!(ParamList::new(vec![]).bind(&module, &[]).unwrap().slots().is_empty());

pub fn presence(&self) -> u64

The presence mask: bit i is set when parameter i received an argument (for a rest parameter, at least one).

Examples

use bytecode_lang::{ModuleBuilder, Param, ParamList, StrId};

let mut m = ModuleBuilder::new();
let x = m.string("x");
let module = m.finish().unwrap();
let list = ParamList::new(vec![Param::normal(x).with_default()]);
assert_eq!(list.bind(&module, &[]).unwrap().presence(), 0);
