Enum PolygonSearchError 

#[non_exhaustive]
pub enum PolygonSearchError {
    InvalidStart {
        point: Point2,
    },
    InvalidGoal {
        point: Point2,
    },
    BudgetExhausted(BudgetExhausted),
}

Request rejected before search, or budget hard stop mid-search.

Pathfinder-level endpoint errors and Self::BudgetExhausted. Unreachable but walkable endpoints produce SearchOutcome::NoPath, not these variants. Static scene defects use PolygonValidationError on validate* / preprocess paths instead.

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.

InvalidStart

Start fails PolygonScene::is_walkable.

Fields

point: Point2

Off-free-space start that was rejected.

InvalidGoal

Goal fails PolygonScene::is_walkable.

Fields

point: Point2

Off-free-space goal that was rejected.

BudgetExhausted(BudgetExhausted)

Caller search budget was exhausted before found/no-path completed.

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.
