Trait DataRequirement 

pub trait DataRequirement<'a> {
    type Borrow: DataBorrow;

    // Required method
    fn fetch(resource_map: &'a ResourceMap) -> Self::Borrow;
}

DataRequirement base trait, which underlies Read and Write requests

Required Associated Types

type Borrow: DataBorrow

Required Methods

fn fetch(resource_map: &'a ResourceMap) -> Self::Borrow

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.
