Trait RowIndex

pub trait RowIndex<ColRange>: Sized + Seal {
    type Target;

    // Required method
    fn get(this: Self, col: ColRange) -> Self::Target;

    // Provided method
    unsafe fn get_unchecked(this: Self, col: ColRange) -> Self::Target { ... }
}

Represents a type that can be used to slice a row, such as an index or a range of indices.

Required Associated Types

type Target

Resulting type of the indexing operation.

Required Methods

fn get(this: Self, col: ColRange) -> Self::Target

Index the row at col.

Provided Methods

unsafe fn get_unchecked(this: Self, col: ColRange) -> Self::Target

Index the row at col, without bound checks.

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.
