Enum PreprocessedGridBuildError 

#[non_exhaustive]
pub enum PreprocessedGridBuildError {
    Hierarchical(HierarchicalGridBuildError),
    NonUniformCost {
        algorithm: &'static str,
        point: Point,
        cost: usize,
    },
}

Error returned when static grid preprocessing fails.

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.

Hierarchical(HierarchicalGridBuildError)

Hierarchical / HPA*-style prep nested under the preprocessed-grid surface.

NonUniformCost

Algorithm requires unit costs on every walkable cell.

Fields

algorithm: &'static str

point: Point

cost: usize

Trait Implementations

impl Eq for PreprocessedGridBuildError

impl Error for PreprocessedGridBuildError

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
