Struct specs::prelude::ResourceId

pub struct ResourceId { /* private fields */ }

The id of a Resource, which simply wraps a type id and a “dynamic ID”. The “dynamic ID” is usually just left 0, and, unless such documentation says otherwise, other libraries will assume that it is always 0; non-zero IDs are only used for special resource types that are specifically defined in a more dynamic way, such that resource types can essentially be created at run time, without having different static types.

Implementations

impl ResourceId

pub fn new<T>() -> ResourceId where
    T: Resource, 

Creates a new resource id from a given type.

pub fn from_type_id(type_id: TypeId) -> ResourceId

Create a new resource id from a raw type ID.

pub fn new_with_dynamic_id<T>(dynamic_id: u64) -> ResourceId where
    T: Resource, 

Creates a new resource id from a given type and a dynamic_id.

This is usually not what you want (unless you’re implementing scripting with shred or some similar mechanism to define resources at run-time).

Creating resource IDs with a dynamic_id unequal to 0 is only recommended for special types that are specifically defined for scripting; most libraries will just assume that resources are identified only by their type.

pub fn from_type_id_and_dynamic_id(
    type_id: TypeId,
    dynamic_id: u64
) -> ResourceId

Create a new resource id from a raw type ID and a “dynamic ID” (see type documentation).
