Enum GridSearchError 

#[non_exhaustive]
pub enum GridSearchError {
    InvalidStart {
        point: Point,
    },
    InvalidGoal {
        point: Point,
    },
    BudgetExhausted(BudgetExhausted),
    StepLimitReached {
        max_steps: usize,
        reached: Point,
    },
}

Failure to execute a grid search request (request validation or hard stop).

Unreachable but valid endpoints produce SearchOutcome::NoPath, not these variants. Caller SearchBudget exhaustion is Self::BudgetExhausted and does not prove unreachability.

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 is out of bounds or not walkable.

Fields

point: Point

InvalidGoal

Goal is out of bounds or not walkable.

Fields

point: Point

BudgetExhausted(BudgetExhausted)

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

StepLimitReached

Flow-field path sampling stopped after max_steps steps without the goal.

Not a general Pathfinder expansion budget API; only crate::flow_field sampling emits this variant.

Fields

max_steps: usize

reached: Point

impl Error for GridSearchError

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
