Struct index_list::Index

pub struct Index(_);

Implementations

impl Index

pub fn is_some(&self) -> bool

Returns true for a valid index

A valid index can be used in IndexList method calls.

pub fn is_none(&self) -> bool

Returns true if the index is invalid

An invalid index should not be used in any IndexList method calls because they will always cause None to be returned.
