Struct LogicalLayoutDescriptor 

pub struct LogicalLayoutDescriptor {
    pub handle: LayoutHandle,
    pub logical_type: LogicalLayoutHandle,
    pub layout: LayoutDescriptor,
}

Layout descriptor with its assigned handle and logical type for RDMA metadata exchange.

This includes the logical layout type (G1, G2, G3, G4) so that remote instances know which physical handle corresponds to which tier.

Fields

handle: LayoutHandle

Unique handle for this layout

logical_type: LogicalLayoutHandle

The logical layout type (G1, G2, G3, G4)

layout: LayoutDescriptor

Serialized layout data (uses Serde, bridged via bincode)

Implementations

impl LogicalLayoutDescriptor

pub fn new( handle: LayoutHandle, logical_type: LogicalLayoutHandle, layout: LayoutDescriptor, ) -> Self

Create a new layout descriptor with handle and logical type.

pub fn new_with_default_type( handle: LayoutHandle, layout: LayoutDescriptor, ) -> Self

Create a layout descriptor with G2 as the default logical type.

This is provided for backwards compatibility with code that doesn’t track logical types. G2 is used as the default since it’s the most common tier for RDMA transfers (GPU memory for KV cache).

For proper RDMA transfers between instances, use new() with the correct logical type from the Worker’s registered handles.
