Struct StateDescriptor 

#[repr(C, align(8))]
pub struct StateDescriptor {
    pub magic: u32,
    pub version: u32,
    pub total_size: u64,
    pub external_ptr: u64,
}

Descriptor stored in _reserved when using external state.

When state is too large to embed, this 24-byte descriptor points to the external GPU memory location.

Fields

magic: u32

Magic number for validation (STATE_DESCRIPTOR_MAGIC).

version: u32

State version number.

total_size: u64

Total size of external state in bytes.

external_ptr: u64

Pointer to external state buffer (GPU address).

Implementations

impl StateDescriptor

pub const fn new( version: u32, total_size: u64, external_ptr: u64, ) -> StateDescriptor

Create a new state descriptor.

pub fn is_valid(&self) -> bool

Check if this descriptor is valid.

pub fn is_external(&self) -> bool

Check if state is external (has external pointer).

pub fn is_embedded(&self) -> bool

Check if state is embedded (no external pointer).
