Enum bitboard_xo::XOError

pub enum XOError {
    PositionError {
        source: XOPosError,
    },
    GameError {
        source: XOGameError,
    },
}

Super Error combining all error in this crate (XOPosError and XOGameError)

both XOPosError and XOGameError can convert to XOError with ? operator

use bitboard_xo::XOError;
fn main() -> Result<(), XOError> {
    use bitboard_xo::{XOPos, XO, XOPosError, XOGameError};

    // ? auto convert XOPosError to XOError
    let result_pos: Result<_, XOPosError> =
        XOPos::col_row(1, 1);
    let pos: XOPos = result_pos?;

    // ? auto convert XOGameError to XOError
    let mut game = XO::new();
    let result_win_state: Result<_, XOGameError> =
        game.play(pos);
    let win_state = result_win_state?;

    Ok(())
}

Trait Implementations

impl Debug for XOError

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Display for XOError

fn fmt(&self, formatter: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Error for XOError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

Deprecated since 1.41.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<XOGameError> for XOError

fn from(source: XOGameError) -> Self

Performs the conversion.

impl From<XOPosError> for XOError

fn from(source: XOPosError) -> Self

Performs the conversion.
