Struct FragmentationMetrics 

pub struct FragmentationMetrics {
    pub total_free_bytes: usize,
    pub largest_free_block: usize,
    pub free_block_count: u32,
}

Measures memory fragmentation of free space.

Fields

total_free_bytes: usize

Total free bytes across all free blocks.

largest_free_block: usize

Size of the largest contiguous free block.

free_block_count: u32

Number of separate free blocks.

Implementations

impl FragmentationMetrics

pub fn new(total_free: usize, largest_block: usize, block_count: u32) -> Self

Creates a new FragmentationMetrics.

pub fn fragmentation_ratio(&self) -> f64

Computes the fragmentation ratio.

Returns 1.0 - (largest_free_block / total_free_bytes). A value of 0.0 means no fragmentation (single contiguous block). A value near 1.0 means high fragmentation.

Returns 0.0 if total_free_bytes is zero.

pub fn average_free_block_size(&self) -> usize

Returns the average free block size, or 0 if there are no free blocks.

Trait Implementations

impl Clone for FragmentationMetrics

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

Performs copy-assignment from source.

impl Debug for FragmentationMetrics

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

Formats the value using the given formatter.

impl Default for FragmentationMetrics

fn default() -> FragmentationMetrics

Returns the “default value” for a type.
