Enum GridEditError 

#[non_exhaustive]
pub enum GridEditError {
    OutOfBounds {
        point: Point,
        width: usize,
        height: usize,
    },
    BlockedCell {
        point: Point,
    },
    ZeroTraversalCost {
        point: Point,
    },
}

Error returned when a requested grid edit violates grid invariants.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

OutOfBounds

Target cell lies outside 0..width × 0..height.

Fields

point: Point

width: usize

height: usize

BlockedCell

Traversal cost cannot be set on a blocked cell.

Fields

point: Point

ZeroTraversalCost

Traversal cost must be strictly positive.

Fields

point: Point

impl Eq for GridEditError

impl Error for GridEditError

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

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
