Enum HierarchicalGridBuildError 

#[non_exhaustive]
pub enum HierarchicalGridBuildError {
    InvalidClusterSize,
    NonUniformCost {
        point: Point,
        cost: usize,
    },
}

Hierarchical preprocess failed (cluster size or non-uniform costs).

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.

InvalidClusterSize

Cluster width/height must be positive for HPA*-style builders.

NonUniformCost

Hierarchical abstracts currently require unit traversal_cost on every walkable cell.

Fields

point: Point

cost: usize

impl Eq for HierarchicalGridBuildError

impl Error for HierarchicalGridBuildError

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
