Implementations
sourceimpl Role
impl Role
sourcepub fn from_char(ch: char) -> Option<Role>
pub fn from_char(ch: char) -> Option<Role>

Examples
use shakmaty::Role;
assert_eq!(Role::from_char('K'), Some(Role::King));
assert_eq!(Role::from_char('n'), Some(Role::Knight));
assert_eq!(Role::from_char('X'), None);
sourcepub fn char(self) -> char
pub fn char(self) -> char

Examples
use shakmaty::Role;
assert_eq!(Role::Rook.char(), 'r');
sourcepub fn upper_char(self) -> char
pub fn upper_char(self) -> char
Gets the uppercase English letter for the piece type.
Examples
