Struct ClosureLayout 

pub struct ClosureLayout {
    pub fn_ptr_offset: usize,
    pub env_offset: usize,
    pub env_size: usize,
    pub arity: usize,
    pub num_captured: usize,
    pub object_layout: ObjectLayout,
}

Detailed layout information for a closure.

Fields

fn_ptr_offset: usize

Byte offset of the function pointer from closure start.

env_offset: usize

Byte offset of the captured environment from closure start.

env_size: usize

Total size of the captured environment in bytes.

arity: usize

Number of parameters the function takes (total arity).

num_captured: usize

Number of captured variables.

object_layout: ObjectLayout

The overall object layout.

Implementations

impl ClosureLayout

pub fn new(arity: usize, num_captured: usize) -> Self

Create a closure layout for a function with the given arity and captured variable count.

pub fn captured_var_offset(&self, idx: usize) -> usize

Byte offset of the i-th captured variable.

Trait Implementations

impl Clone for ClosureLayout

fn clone(&self) -> ClosureLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClosureLayout

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

Formats the value using the given formatter.

impl Display for ClosureLayout

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

Formats the value using the given formatter.

impl PartialEq for ClosureLayout

fn eq(&self, other: &ClosureLayout) -> 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.
