Struct FlatClosure 

pub struct FlatClosure {
    pub fn_index: u32,
    pub arity: u32,
    pub env: Vec<u64>,
}

A flat, heap-allocated closure that can be serialized (no dyn fn ptrs).

Fields

fn_index: u32

Function index (into a global function table).

arity: u32

Arity.

env: Vec<u64>

Environment values (limited to simple types here: u64).

Implementations

impl FlatClosure

pub fn new(fn_index: u32, arity: u32, env: Vec<u64>) -> Self

Create a new flat closure.

pub fn serialize(&self) -> Vec<u8>

Serialize to bytes.

pub fn deserialize(data: &[u8]) -> Option<Self>

Deserialize from bytes.

pub fn is_thunk(&self) -> bool

Whether this is a thunk (arity == 0).

pub fn env_size(&self) -> usize

Env size.
