Struct Classes 

pub struct Classes { /* private fields */ }

Container for all entity classes in a replay.

Classes define the types of entities that exist in the game. Each entity belongs to a class which specifies:

• What properties it has
• How those properties are encoded
• The class name (e.g., “CDOTA_Unit_Hero_Axe”)

Examples

Iterating all classes

use source2_demo::prelude::*;

for class in ctx.classes().iter() {
    println!("Class ID {}: {}", class.id(), class.name());
}

Finding a specific class

use source2_demo::prelude::*;

// Get by class name
let hero_class = ctx.classes().get_by_name("CDOTA_Unit_Hero_Axe")?;
println!("Found class: {}", hero_class.name());

// Get by ID
let class = ctx.classes().get_by_id(42)?;

Implementations

impl Classes

pub fn iter(&self) -> impl Iterator<Item = &Class>

Returns an iterator over all classes.

This allows you to discover all entity types in the replay.

pub fn get_by_id(&self, id: usize) -> Result<&Class, ClassError>

Gets a class by its numeric ID.

Arguments

• id - The numeric class ID

Errors

Returns ClassError::ClassNotFoundById if no class with the given ID exists.

Examples

use source2_demo::prelude::*;

let class = ctx.classes().get_by_id(42)?;
println!("Class name: {}", class.name());

pub fn get_by_name(&self, name: &str) -> Result<&Class, ClassError>

Gets a class by its name.

This is the most common way to find entity classes since you typically know the class name you’re looking for (e.g., “CDOTA_Unit_Hero_Axe”).

Arguments

• name - The class name (case-sensitive, e.g., “CDOTA_PlayerResource”)

Errors

Returns ClassError::ClassNotFoundByName if no class with the given name exists.

Examples

use source2_demo::prelude::*;

// Find hero class
let hero_class = ctx.classes().get_by_name("CDOTA_Unit_Hero_Axe")?;

// Find player resource class
let resource = ctx.classes().get_by_name("CDOTA_PlayerResource")?;

Trait Implementations

impl Default for Classes

fn default() -> Classes

Returns the “default value” for a type.

impl Display for Classes

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

Formats the value using the given formatter.
