    // Required method
    fn try_get_xy<T: ToPrimitive>(
        &self,
        x: T,
        y: T,
    ) -> Result<&Self::Item, IndexError>;

    // Provided methods
    fn get_xy<T: ToPrimitive>(&self, x: T, y: T) -> &Self::Item { ... }
    fn get_p<T: ToPrimitive, P: IntoTuple2<T>>(&self, p: P) -> &Self::Item { ... }
    fn try_get_p<T: ToPrimitive, P: IntoTuple2<T>>(
        &self,
        p: P,
    ) -> Result<&Self::Item, IndexError> { ... }
}

A trait which provides common access interfaces to 2D Array type.

Required Associated Types

type Item

Required Methods

fn try_get_xy<T: ToPrimitive>( &self, x: T, y: T, ) -> Result<&Self::Item, IndexError>

Provided Methods

fn get_xy<T: ToPrimitive>(&self, x: T, y: T) -> &Self::Item

fn get_p<T: ToPrimitive, P: IntoTuple2<T>>(&self, p: P) -> &Self::Item

fn try_get_p<T: ToPrimitive, P: IntoTuple2<T>>( &self, p: P, ) -> Result<&Self::Item, IndexError>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
