Struct SystemInfo

pub struct SystemInfo {
    pub os_type: String,
    pub cpu_cores: usize,
    pub total_memory_bytes: u64,
    pub is_debug: bool,
    pub is_wasm: bool,
    pub target_arch: String,
}

System information structure

Contains runtime-detected system hardware and environment information, used for allocator selection decisions.

Fields

• os_type - Operating system type (linux, macos, windows, etc.)
• cpu_cores - CPU core count (including hyperthreaded cores)
• total_memory_bytes - Total memory in bytes
• is_debug - Whether this is a Debug build
• is_wasm - Whether this is a WASM environment
• target_arch - Target architecture (x86_64, aarch64, etc.)

Example

use auto_allocator;

let info = auto_allocator::get_allocator_info();
let sys = &info.system_info;

println!("Operating system: {}", sys.os_type);
println!("CPU cores: {}", sys.cpu_cores);
println!("Total memory: {}", auto_allocator::format_memory_size(sys.total_memory_bytes));

Fields

os_type: String

Operating system type

Examples: “linux”, “macos”, “windows”, “unknown”

cpu_cores: usize

CPU core count

Detected via std::thread::available_parallelism(), includes hyperthreaded core count

total_memory_bytes: u64

Total memory in bytes

System total physical memory, used for hardware specification assessment. Use format_memory_size() to format as human-readable string.

is_debug: bool

Whether this is a Debug build

Debug builds automatically select system allocator for faster compilation

is_wasm: bool

Whether this is a WASM environment

WASM environments automatically select system allocator for compatibility

target_arch: String

Target architecture

Examples: “x86_64”, “aarch64”, “riscv32”, “wasm32”

Trait Implementations

impl Clone for SystemInfo

fn clone(&self) -> SystemInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SystemInfo

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

Formats the value using the given formatter.
