Struct MemoryTracker

pub struct MemoryTracker { /* private fields */ }

Core memory tracking functionality.

The MemoryTracker maintains records of all memory allocations and deallocations, provides statistics, and supports exporting data in various formats.

Implementations

impl MemoryTracker

pub fn new() -> Self

Create a new memory tracker.

pub fn track_allocation(&self, ptr: usize, size: usize) -> TrackingResult<()>

Track a new memory allocation.

pub fn track_deallocation(&self, ptr: usize) -> TrackingResult<()>

Track a memory deallocation.

pub fn associate_var( &self, ptr: usize, var_name: String, type_name: String, ) -> TrackingResult<()>

Associate a variable name and type with an allocation.

pub fn get_stats(&self) -> TrackingResult<MemoryStats>

Get current memory usage statistics.

pub fn get_active_allocations(&self) -> TrackingResult<Vec<AllocationInfo>>

Get all currently active allocations.

pub fn get_allocation_history(&self) -> TrackingResult<Vec<AllocationInfo>>

Get the complete allocation history.

pub fn get_memory_by_type(&self) -> TrackingResult<Vec<TypeMemoryUsage>>

Get memory usage grouped by type.

pub fn export_to_json<P: AsRef<Path>>(&self, path: P) -> TrackingResult<()>

Export memory data to JSON format with hierarchical structure.

pub fn export_memory_analysis<P: AsRef<Path>>( &self, path: P, ) -> TrackingResult<()>

Export memory analysis visualization showing variable names, types, and usage patterns. This creates a comprehensive memory analysis with call stack analysis, timeline, and categorization.

Arguments

• path - Output path for the memory analysis SVG file (recommended: “program_name_memory_analysis.svg”)

pub fn export_lifecycle_timeline<P: AsRef<Path>>( &self, path: P, ) -> TrackingResult<()>

Export interactive lifecycle timeline showing variable lifecycles and relationships. This creates an advanced timeline with variable birth, life, death, and cross-section interactivity.

Arguments

• path - Output path for the lifecycle timeline SVG file (recommended: “program_name_lifecycle.svg”)

pub fn export_to_svg<P: AsRef<Path>>(&self, path: P) -> TrackingResult<()>

👎Deprecated since 0.1.0: Use export_memory_analysis instead

Legacy export method for backward compatibility. Redirects to the new memory analysis export.

Arguments

• path - Output path for the SVG file

Trait Implementations

impl Default for MemoryTracker

fn default() -> Self

Returns the “default value” for a type.
