Trait ViewLen 

pub trait ViewLen {
    // Required method
    fn len(&self) -> usize;

    // Provided method
    fn is_empty(&self) -> bool { ... }
}

The number of rows addressable through a row-loop view.

Required Methods

fn len(&self) -> usize

Return the number of addressable rows.

Provided Methods

fn is_empty(&self) -> bool

Return whether the view contains no rows.

Dyn Compatibility

This trait is dyn compatible.

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