Struct AssetId 

pub struct AssetId(/* private fields */);

Unique identifier for an asset type at runtime.

AssetId wraps a TypeId to identify asset types. This is used internally for asset storage, loader registration, and type-safe access.

Unlike Handle, which identifies a specific asset instance, AssetId identifies an asset type.

Example

use goud_engine::assets::{Asset, AssetId};

struct Texture { /* ... */ }
impl Asset for Texture {}

struct Mesh { /* ... */ }
impl Asset for Mesh {}

let tex_id = AssetId::of::<Texture>();
let mesh_id = AssetId::of::<Mesh>();

assert_ne!(tex_id, mesh_id);
assert_eq!(tex_id, AssetId::of::<Texture>());

FFI Considerations

AssetId is NOT FFI-safe (contains TypeId). For FFI, use the AssetType enum or string-based type names.

Implementations

impl AssetId

pub fn of<T: Asset>() -> Self

Returns the AssetId for a specific asset type.

Example

use goud_engine::assets::{Asset, AssetId};

struct MyAsset;
impl Asset for MyAsset {}

let id = AssetId::of::<MyAsset>();

pub fn of_raw<T: 'static>() -> Self

Returns the AssetId for any 'static type.

This is useful for internal operations where the type may not implement Asset yet (e.g., during registration).

Example

use goud_engine::assets::AssetId;

let id = AssetId::of_raw::<String>();

pub fn type_id(&self) -> TypeId

Returns the underlying TypeId.

Example

use goud_engine::assets::{Asset, AssetId};
use std::any::TypeId;

struct MyAsset;
impl Asset for MyAsset {}

let id = AssetId::of::<MyAsset>();
assert_eq!(id.type_id(), TypeId::of::<MyAsset>());

Trait Implementations

impl Clone for AssetId

fn clone(&self) -> AssetId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AssetId

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

Formats the value using the given formatter.

impl Display for AssetId

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

Formats the value using the given formatter.

impl Hash for AssetId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for AssetId

fn cmp(&self, other: &AssetId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for AssetId

fn eq(&self, other: &AssetId) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for AssetId

fn partial_cmp(&self, other: &AssetId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
