Struct SystemCapabilities 

pub struct SystemCapabilities {
    pub platform: Platform,
    pub kernel_version: Option<KernelVersion>,
    pub cpu_count: usize,
    pub physical_cores: usize,
    pub numa_nodes: usize,
    pub cache_line_size: usize,
    pub cpu_features: CpuFeatures,
    pub io_uring: IoUringCapabilities,
    pub xdp: XdpCapabilities,
    pub storage: StorageInfo,
    pub memory: MemoryInfo,
}

Detected system capabilities.

This struct aggregates all detected hardware and software capabilities into a single view, making it easy to configure LaminarDB optimally.

Detection is performed lazily and cached for efficiency.

Fields

platform: Platform

Detected platform.

kernel_version: Option<KernelVersion>

Detected kernel version (Linux/macOS only).

cpu_count: usize

Number of logical CPUs.

physical_cores: usize

Number of physical CPU cores.

numa_nodes: usize

Number of NUMA nodes.

cache_line_size: usize

Cache line size in bytes.

cpu_features: CpuFeatures

CPU feature flags.

io_uring: IoUringCapabilities

io_uring capabilities.

xdp: XdpCapabilities

XDP capabilities.

storage: StorageInfo

Storage information (for data directory).

memory: MemoryInfo

Memory information.

Implementations

impl SystemCapabilities

pub fn detect() -> &'static Self

Detect all system capabilities.

This method is safe to call multiple times - results are cached after the first detection.

pub fn detect_uncached() -> Self

Detect capabilities without caching.

Use detect() for normal usage.

pub fn detect_with_storage<P: AsRef<Path>>(data_path: P) -> Self

Detect capabilities with storage detection for a specific path.

pub fn update_storage<P: AsRef<Path>>(&mut self, data_path: P)

Update storage detection for a new path.

pub fn recommended_config(&self) -> RecommendedConfig

Get recommended configuration based on detected capabilities.

pub fn summary(&self) -> String

Generate a human-readable summary of all capabilities.

pub fn is_fully_optimized(&self) -> bool

Check if all advanced features are available.

pub fn meets_minimum_requirements(&self) -> bool

Check if the system meets minimum requirements for LaminarDB.

pub fn missing_features(&self) -> Vec<&'static str>

Get a list of missing features that would improve performance.

pub fn log_summary(&self)

Log the detected capabilities.

Trait Implementations

impl Clone for SystemCapabilities

fn clone(&self) -> SystemCapabilities

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SystemCapabilities

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

Formats the value using the given formatter.
