Struct ResourceGuard 

pub struct ResourceGuard { /* private fields */ }

Unified resource guard for monitoring all system resources.

Implementations

impl ResourceGuard

pub fn new(config: ResourceGuardConfig) -> Self

Create a new resource guard with the given configuration.

pub fn default_guard() -> Self

Create a resource guard with default configuration.

pub fn with_memory_limit(limit_mb: usize) -> Self

Create a resource guard with specified memory limit.

pub fn disabled() -> Self

Create a disabled resource guard.

pub fn shared(config: ResourceGuardConfig) -> Arc<Self>

Create an Arc-wrapped resource guard for sharing across threads.

pub fn check(&self) -> SynthResult<DegradationLevel>

Check all resources (memory, disk, CPU). Returns Ok with current degradation level or Err if hard limits exceeded.

pub fn check_now(&self) -> SynthResult<DegradationLevel>

Force an immediate check of all resources (bypasses interval).

pub fn get_actions(&self) -> DegradationActions

Get actions to take based on current degradation level.

pub fn is_degraded(&self) -> bool

Check if currently degraded (not Normal).

pub fn degradation_level(&self) -> DegradationLevel

Get current degradation level.

pub fn stats(&self) -> ResourceStats

Get combined resource statistics.

pub fn pre_check(&self) -> PreCheckResult

Pre-check before a potentially expensive operation. Returns recommended action based on current resource state.

pub fn check_before_write(&self, estimated_bytes: u64) -> SynthResult<()>

Pre-check before writing data.

pub fn record_write(&self, bytes: u64)

Record bytes written (for tracking).

pub fn memory(&self) -> &MemoryGuard

Get reference to memory guard.

pub fn disk(&self) -> &DiskSpaceGuard

Get reference to disk guard.

pub fn cpu(&self) -> &CpuMonitor

Get reference to CPU monitor.

pub fn degradation(&self) -> &DegradationController

Get reference to degradation controller.

pub fn maybe_throttle(&self)

Apply throttle delay if CPU is overloaded.

pub fn reset_stats(&self)

Reset all statistics (for testing).

pub fn is_available() -> bool

Check if resource monitoring is available on this platform.

pub fn current_memory_mb(&self) -> usize

Get current memory usage in MB.

pub fn available_disk_mb(&self) -> usize

Get current available disk space in MB.

pub fn current_cpu_load(&self) -> f64

Get current CPU load.

Trait Implementations

impl Debug for ResourceGuard

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

Formats the value using the given formatter.

impl Default for ResourceGuard

fn default() -> Self

Returns the “default value” for a type.
