Struct EvolutionMap 

pub struct EvolutionMap {
    pub modified: HashMap<usize, Vec<usize>>,
    pub generated: HashMap<usize, Vec<usize>>,
    pub deleted: HashSet<usize>,
}

Tracks how faces evolve through a modeling operation.

After a boolean, fillet, or other operation, this map records:

• modified: input face -> output faces that replace it
• generated: input face -> new faces created adjacent to it
• deleted: input faces that were completely removed

Fields

modified: HashMap<usize, Vec<usize>>

Input face -> output faces that are modified versions of it.

generated: HashMap<usize, Vec<usize>>

Input face -> new faces generated from it (e.g., blend faces from fillet).

deleted: HashSet<usize>

Input faces that were completely removed.

Implementations

impl EvolutionMap

pub fn new() -> Self

Create an empty evolution map.

pub fn add_modified(&mut self, input: usize, output: usize)

Record that input was modified into output.

pub fn add_generated(&mut self, input: usize, output: usize)

Record that output was generated from input.

pub fn add_deleted(&mut self, input: usize)

Record that input was deleted.

pub fn to_json(&self) -> String

Serialize to JSON without serde.

Produces a JSON object with modified, generated, and deleted fields.

Trait Implementations

impl Default for EvolutionMap

fn default() -> EvolutionMap

Returns the “default value” for a type.
