Enum takuzu::GridSizeError

pub enum GridSizeError {
    EmptyGrid,
    NotASquare {
        line: usize,
        found: usize,
        expected: usize,
    },
    OddNumberSize(usize),
}

An error returned when the grid is not properly sized.

Variants

EmptyGrid

The grid is empty.

NotASquare

The grid is not a square.

Fields of NotASquare

line: usize

Line on which the error occured.

found: usize

Number of characters found.

expected: usize

Number of characters expected.

OddNumberSize(usize)

The size of the grid is an odd number. The field contains the number of lines in the grid.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
