Struct Class 

pub struct Class { /* private fields */ }

Entity class definition.

Represents the type and structure of an entity. Classes define:

• Class ID: Numeric identifier
• Class name: Human-readable type name (e.g., “CDOTA_Unit_Hero_Axe”)
• Serializer: Defines which properties exist and how they’re encoded

Class Name Patterns

Entity class names follow patterns that help identify their type:

• CDOTA_Unit_Hero_* - Dota 2 heroes
• CDOTA_Unit_* - Dota 2 NPCs and units
• CDOTA_Item_* - Dota 2 item holders
• CDOTA_* - Other Dota 2 entities
• CCitadelPlayerPawn - Deadlock players
• CPlayer_* - CS2 players

Examples

Using class information

use source2_demo::prelude::*;

let class = entity.class();
println!("Entity ID: {}", class.id());
println!("Entity name: {}", class.name());

// Check entity type
if class.name().starts_with("CDOTA_Unit_Hero_") {
    println!("This is a hero!");
}

Finding all entities of a class type

use source2_demo::prelude::*;

// Find all heroes
let heroes: Vec<&Entity> = ctx.entities()
    .iter()
    .filter(|e| e.class().name().starts_with("CDOTA_Unit_Hero_"))
    .collect();

Implementations

impl Class

pub fn name(&self) -> &str

Returns the human-readable name of this class.

Examples: “CDOTA_Unit_Hero_Axe”, “CDOTA_PlayerResource”

Examples

use source2_demo::prelude::*;

match class.name() {
    "CDOTA_PlayerResource" => println!("Found player resource"),
    name if name.starts_with("CDOTA_Unit_Hero_") => println!("Found hero"),
    _ => println!("Other entity type"),
}

pub fn id(&self) -> i32

Returns the numeric ID of this class.

Each class has a unique numeric ID assigned when the replay is parsed. This ID is used internally for efficient entity classification.

Examples

use source2_demo::prelude::*;

println!("Class ID: {}", class.id());

Trait Implementations

impl Clone for Class

fn clone(&self) -> Class

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for Class

fn default() -> Class

Returns the “default value” for a type.
