Required methods

fn truncate(&mut self, _len: usize) -> Result<(), GeneError>

Shortens the array, keeping the first len elements and dropping the rest.

fn shift(&mut self, n: usize) -> Result<(), GeneError>

Shift the array, by discarding the first n elements from the front.

fn for_each<F>(&self, f: F) -> Result<(), GeneError> where
    F: FnMut(Result<Self::Value, GeneError>), 

Execute the given closure for each value in the array
