Trait AltrepLen 

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

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

Base trait for ALTREP data types. All ALTREP types must provide length.

Required Methods

fn len(&self) -> usize

Returns the length of this ALTREP vector.

Provided Methods

fn is_empty(&self) -> bool

Returns true if the vector is empty.
