Trait Grid2Ref

pub trait Grid2Ref: Grid2 {
    // Required method
    fn idx<I>(&self, coord: I) -> &Self::Item
       where I: Into<Vector2<i32>>;

    // Provided method
    fn try_idx<I>(&self, coord: I) -> Option<&Self::Item>
       where I: Into<Vector2<i32>> { ... }
}

2D grid read by reference.

Required Methods

fn idx<I>(&self, coord: I) -> &Self::Item

where I: Into<Vector2<i32>>,

Provided Methods

fn try_idx<I>(&self, coord: I) -> Option<&Self::Item>

where I: Into<Vector2<i32>>,

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.
