Struct LayoutHandle 

pub struct LayoutHandle(/* private fields */);

Unique handle for a layout combining worker_id and layout_id.

The handle encodes:

• Bits 0-63: worker_id (u64)
• Bits 64-79: layout_id (u16)
• Bits 80-127: Reserved (48 bits, currently unused)

Implementations

impl LayoutHandle

pub fn new(worker_id: u64, layout_id: u16) -> Self

Create a new layout handle from worker_id and layout_id.

Arguments

• worker_id - Unique identifier for the worker (0-63 bits)
• layout_id - Layout identifier within the worker (64-79 bits)

pub fn worker_id(&self) -> u64

Extract the worker_id from this handle.

pub fn layout_id(&self) -> u16

Extract the layout_id from this handle.

pub fn as_u128(&self) -> u128

Get the raw u128 value.

pub fn from_u128(value: u128) -> Self

Reconstruct a handle from a raw u128 value.

This preserves all bits including reserved bits, and is intended for deserialization roundtrips with as_u128().
