Enum HostResidency 

pub enum HostResidency {
    Pinned,
    Locked,
    Pageable,
}

Residency class of one layer’s expert bank.

The string forms are the wire values FreeToken uses ("pinned" / "locked" / "pageable"), so a label written by either side reads the same.

Variants

Pinned

Page-locked and device-addressable: the only class the GPU expert path can DMA from.

Locked

Resident (unswappable) but CPU-only: no device address.

Pageable

An ordinary mapping; may be swapped out.

Implementations

impl HostResidency

pub fn as_str(self) -> &'static str

pub fn from_label(label: &str) -> Option<Self>

The inverse of as_str. Unknown text is None rather than a default: a label nobody wrote is not the same as a label that says “pinned”, and guessing Pinned would promise a device address that does not exist.

pub fn is_device_addressable(self) -> bool

Whether the GPU can read this bank directly. The single question every consumer of a label actually asks.
