Trait Data 

pub trait Data<'borrow>:
    DataAccess
    + DataAccessDyn
    + Send {
    // Required method
    fn borrow(item_id: &'borrow ItemId, resources: &'borrow Resources) -> Self;
}

Defines the logic to instantiate and retrieve runtime data.

Note for API Consumers

This trait is implemented by using the Data derive.

Required Methods

fn borrow(item_id: &'borrow ItemId, resources: &'borrow Resources) -> Self

Borrows each of Self’s fields from the provided Resources.

This takes in the item_id, so that the type that implements this trait may further filter specific data within the borrowed data, scope to the item.

Parameters

• item_id: ID of the item this borrow is used for.
• resources: Any map to borrow the data from.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
