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".
