Struct List

Source

pub struct List { /* private fields */ }

Expand description

A proper list.

Conversion to this type guarantees that a type is a proper list and allows for fast retrieval of the length or any individual element of the list.

§Performance

This is done by copying the list into a Vec, which can be a quite expensive operation, so only use this if you need all elements of the list.
