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

2026-09-25: Directory of the per-layer KV files.

bytes: u64

2026-09-25: Disk budget in bytes; the server passes --high-speed-swap-gb × 2^30. validate requires it to be non-zero, and nothing in this crate reads it otherwise.

resident_blocks: u32

2026-09-25: Scratch-pool slot count; also the attention tile capacity and the eviction policy’s capacity.

rank: u32

2026-09-25: Predictor low-rank dimension r.

qd: u32

2026-09-25: io_uring queue depth; the portable backend ignores it.

graph: bool

2026-09-25: Capture the per-layer body in a CUDA graph and replay it. The server sets it unless --no-high-speed-swap-graph is given.

projection_seed: u64

2026-09-25: Seed of the predictor’s projection matrix.

Implementations

impl HighSpeedSwapConfig

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

2026-09-25: Range checks: bytes and resident_blocks non-zero, rank in 1..=128, qd in 1..=64. The directory is not checked here.

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

2026-09-25: validate, then create the directory if it is missing.
