Implementations

impl Rank

pub fn new(index: u32) -> Rank

Gets a Rank from an integer index.

Panics

Panics if the index is not in the range 0..=7.

pub unsafe fn new_unchecked(index: u32) -> Rank

Gets a Rank from an integer index.

Safety

It is the callers responsibility to ensure the index is in the range 0..=7.

pub fn from_char(ch: char) -> Option<Rank>

pub fn char(self) -> char

pub fn offset(self, delta: i32) -> Option<Rank>

pub fn distance(self, other: Rank) -> u32

pub fn flip_diagonal(self) -> File

pub fn flip_anti_diagonal(self) -> File

pub const ALL: [Rank; 8] = [Rank::First, Rank::Second, Rank::Third, Rank::Fourth, Rank::Fifth, Rank::Sixth, Rank::Seventh, Rank::Eighth]

Trait Implementations

impl Clone for Rank

fn clone(&self) -> Rank

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Rank

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for Rank

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for Rank

fn hash<__H>(&self, state: &mut __H)where
    __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,

Feeds a slice of this type into the given Hasher.

impl Ord for Rank

fn cmp(&self, other: &Rank) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Rank> for Rank

fn eq(&self, other: &Rank) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<Rank> for Rank

fn partial_cmp(&self, other: &Rank) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
