Struct HostTopology 

pub struct HostTopology {
    pub adapters: Vec<AdapterDesc>,
    pub topology: HostMemoryTopology,
    pub host_ram_bytes: u64,
    pub host_ram_available_bytes: u64,
    pub cpu_cores: usize,
    pub os_floor_bytes: u64,
    pub usable_model_budget_bytes: u64,
}

The sensed host: adapters, topology, host memory, and the bounded OS floor (D24).

Fields

adapters: Vec<AdapterDesc>

topology: HostMemoryTopology

host_ram_bytes: u64

host_ram_available_bytes: u64

cpu_cores: usize

os_floor_bytes: u64

Hard floor reserved for the OS/display (D24): discrete → VRAM display floor; unified → host floor.

usable_model_budget_bytes: u64

Best-effort memory the LLM may inhabit after the floor (discrete: VRAM−floor; unified: RAM−floor).

Implementations

impl HostTopology

pub fn has_heterogeneous_overflow(&self) -> bool

True when there is both a discrete GPU and a (system-RAM-backed) integrated GPU — the heterogeneous-overflow opportunity (H3): the iGPU can host overflow layers in system RAM.

pub fn summary(&self) -> String

One-line-per-field human summary for logs / the progress record.

Trait Implementations

impl<'de> Deserialize<'de> for HostTopology

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for HostTopology

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,
