Struct RuntimeStats 

pub struct RuntimeStats {
    pub num_pages: usize,
    pub num_textures: usize,
    pub total_page_area: u64,
    pub total_used_area: u64,
    pub total_free_area: u64,
    pub occupancy: f64,
    pub num_free_rects: usize,
}

Runtime statistics for an atlas session.

Fields

num_pages: usize

Number of pages currently allocated.

num_textures: usize

Number of textures currently in the atlas.

total_page_area: u64

Total area of all pages (width * height * num_pages).

total_used_area: u64

Total area occupied by textures (sum of all used slots).

total_free_area: u64

Total free area available for new textures.

occupancy: f64

Occupancy ratio: used_area / total_page_area (0.0 to 1.0).

num_free_rects: usize

Number of free rectangles/segments (fragmentation indicator).

Implementations

impl RuntimeStats

pub fn summary(&self) -> String

Returns a human-readable summary of the statistics.

pub fn fragmentation(&self) -> f64

Returns the fragmentation ratio (higher = more fragmented). Calculated as: num_free_rects / (total_free_area / 1000) Lower is better (fewer, larger free blocks).

pub fn waste_percentage(&self) -> f64

Returns the waste percentage (0.0 to 100.0).

Trait Implementations

impl Clone for RuntimeStats

fn clone(&self) -> RuntimeStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RuntimeStats

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

Formats the value using the given formatter.
