Methods
impl Rank
[src]
fn from_index(i: usize) -> Rank
Convert a usize
into a Rank
(the inverse of to_index). If the number is > 7, wrap
around.
fn down(&self) -> Rank
Go one rank down. If impossible, wrap around.
fn up(&self) -> Rank
Go one file up. If impossible, wrap around.
fn to_index(&self) -> usize
Convert this Rank
into a usize
between 0 and 7 (inclusive).
