Struct HighSpeedSwapConfig 

pub struct HighSpeedSwapConfig {
    pub dir: PathBuf,
    pub bytes: u64,
    pub resident_blocks: u32,
    pub rank: u32,
    pub qd: u32,
    pub graph: bool,
    pub projection_seed: u64,
}

Fields

dir: PathBuf

--high-speed-swap-dir: directory where per-layer KV files live.

bytes: u64

--high-speed-swap-bytes: total disk budget; the layout fails fast if the budget can’t fit num_layers × bytes_per_layer.

resident_blocks: u32

--high-speed-swap-resident-blocks: HBM scratch slot count. The scratch pool allocates exactly this many slots × per-slot bytes.

rank: u32

--high-speed-swap-rank: predictor low-rank dimension.

qd: u32

--high-speed-swap-qd: io_uring submission queue depth. Phase-3 shows QD=8 reaches 3.4 GB/s on this hardware (random 64 KiB).

graph: bool

--high-speed-swap-graph: capture the per-layer body in a CUDA graph and replay (Phase 4).

projection_seed: u64

Predictor seed; when omitted in CLI we’d error rather than default.

Implementations

impl HighSpeedSwapConfig

pub fn validate(&self) -> Result<()>

Validate cross-field invariants. Returns Ok only if the config is internally consistent and the directory is plausibly usable.

pub fn validate_and_prepare(&self) -> Result<()>

Validate, then ensure the directory exists or can be created.

Trait Implementations

impl Clone for HighSpeedSwapConfig

fn clone(&self) -> HighSpeedSwapConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HighSpeedSwapConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for HighSpeedSwapConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.
